MRI through astonomy
2008-08-26 02:51:00 Astronomers from the University of Edinburgh are collaborating with clinicians in trying to apply their expertise in fuzzy image processing to improve the output of MRI machines. The algorithmic techniques, though not specified, are probably based on speckle imaging methods that, thanks to modern computers, have been used in astronomy for a couple decades.MRI scanning can record images of any part of the body from several angles and is used to examine organs or tissue. Patients who undergo scans may have to lie still for half-an-hour or more, while the scanner records successive layered images of their body, much like a slow-exposure photograph. If the patient moves, the images become distorted.The astronomy algorithm corrects distortions caused by movement or caused by the scanner. This makes the technique especially suitable for use with children or seriously ill patients, and avoids patients having to undergo repeat scans to get accurate results.Once an MRI scan is complete, it ...
digital light box
2008-08-26 02:46:00 BrainLAB AG, out of Feldkirchen, Germany has recently installed its first Digital Light box radiology system in a Munich hospital. Designed to be installed in radiology departments, clinical floors, and operating rooms, the system behaves like a giant iPhone, simultaneously displaying volumetric images from various imaging modalities along with patient information.Digital Lightbox replaces the conventional light box used to observe analog x-ray images. Connected to the hospital PACS, the new digital platform can be installed both in meeting rooms and in operating rooms, where clinicians can then access, manipulate, and utilize data for surgery planning. By displaying the human body in 3D, Digital Lightbox helps clinicians to more clearly demonstrate to patients what effects a disease can have and which procedures may be necessary.Digital Lightbox enables clinicians to select the most valuable images from large amounts of existing medical data.

MRI tracks stem cells in the heart.
2008-08-26 02:42:00 Now for the first time, researchers have tracked the stem cells in mice using magnetic resonance imaging (MRI) from their bone marrow origin to the injured site. This opens up the possibility of finding some therapeutic treatment to direct these cells after a heart attack.Mesenchymal stem cells, or MSCs, are found in the bone marrow and can differentiate into certain cell types. They have been detected around heart injuries following a myocardial infarction (heart attack), but whether they come to regenerate heart tissue or to promote healing is still under debate.Using a series of MRI scans, Tom Hu and colleagues at the Medical College of Georgia in Augusta, GA, have tracked MS?s in a sample of mice. The researchers first transplanted into the bone marrow a few hundred thousand MSCs that had been labeled with both iron-oxide (a molecule that essentially shades out the MRI signal) and a special protein that fluoresces when exposed to blue light. The team then operated on all of the ... More About: Heart , Tracks , Stem Cells , Stem , The Heart

Thank you to The Beatles for the First CAT Scan machine
2008-07-24 01:43:00 As a direct result of The Beatles ? success, Dr Timmis claimed, the scanner?s inventor, Sir Godfrey Hounsfield, was able to devote about four years developing the scanner from its 1968 prototype, to something that could be used in a clinical setting. His work was done in the Central Research Laboratory, a facility near Heathrow airport that was part of the EMI Group. Having sold 200 million of the Fab Four?s singles, (at seven inches, almost enough vinyl to stretch the length of the equator) the Beatles? record company, EMI, was able to fund Hounsfield to do his research and the CT scanner was ready be used in hospitals in the 1970?s.

2008-06-22 09:59:00 You ever have one of thoose days that you just wanted to put a 10 penny nail into your bladder? What? I know this sounds crazy but that is exactly what this woman did. The pt came into the ER with slurred speech. The CT scan from the night before had revealed a hypodense area in her brain therefore an MRI was ordered. Before the MRI could be performed the patient had to be Xrayed to find out if she did have a nail in her body. The patient reported it was in her Uterous but upon Ultrasound localization it was found to be in her bladder. (source NEJM). ??Read more here to find out why? More About: Nail , Penny
Gastric Tumors
2008-05-04 20:54:00 Gastric tumors may be classified as benign or malignant on the basis of their biologic behavior; epithelial and mesenchymal tumors may be similarly classified on the basis of their origin. More than 95% of malignant tumors of the stomach are adenocarcinomas . The remaining malignant tumors include lymphoma, sarcoma (eg, malignant gastrointestinal stromal tumor), carcinoid tumor, metastasis, and so on. Between 85% and 90% of gastric tumors are benign . About half of these benign tumors are mucosal lesions (mostly hyperplastic or adenomatous polyps) and about half are mesenchymal tumors .Mesenchymal tumors of the gastrointestinal tract are divided into two broad groups. The first group consists of tumors that are identical to those arising in the somatic soft tissue. These include smooth muscle tumors (eg, leiomyoma, leiomyosarcoma), neural tumors (eg, schwannoma, neurofibroma, plexosarcoma), lipocytic tumors (eg, lipoma, liposarcoma), tumors originating from vascular and perivascular...
thoracic aorta disection
2008-05-04 15:54:00 Aortic dissection is the most common catastrophe affecting the aorta. The aorta is the largest artery of the body through which blood leaves the heart to deliver oxygenated blood to the rest of the body. It occurs in about 24 people per million each year in the U.S. It is caused when the inner layer of the aortic wall tears and then peels or separates away from the next layer of the aorta. This creates two channels; the original aortic channel for blood flow (the true lumen) is still present while the peeling away of the outer layer in the dissection creates a new additional flow channel (the false lumen).Symptoms of Aortic DissectionLocation of Pain:Chest painBack painFlank painAbdominal painLeg painQuality of PainPain that is tearing or sharpAbrupt onset of painPain that migrates or radiatesNeurological DeficitsComa/Altered consciousnessParalysisExtremity numbnessDifficulty with speaking or slurred speechLight-headedness/FaintingDifficulty breathing/shortness of breathThere are th...

Stewart-Treves syndrome is a rare, deadly cutaneous angiosarcoma????..
2008-03-08 04:02:00 I scanned a patient with the diagnosis of angiosarcoma. I was not familiar with the disease and had to do a little research before we did the procedure. She had a history of lymphedema for 13 years after her breast surgery for cancer. Her entire right arm was swollen. Her doctor had done a biopsy on two lesions on her arm and confirmed angiosacroma. She had a CT of the Chest and A MRI of the Forearm and Humerus. Here is some background info on Angiosacroma.this is not the patient I scanned it is only an example in angiosarcomaStewart -Treves syndrome is a rare, deadly cutaneous angiosarcoma that develops in long-standing chronic lymphedema. Most commonly, this tumor is a result of lymphedema induced by radical mastectomy to treat breast cancer. Unfortunately, although the breast cancer may be cured with such radical surgery, this second primary cancer may be responsible for the patient?s worsening course.

Cardiac CTA visualizes cardiovascular disease as well as interventional hea
2008-02-03 16:29:00 January 30, 2008Last night I had the privilege to listen to David Bush MD from John Hopkins speak at Parrish Medical Center. He was very informative about the topic of heart disease and Cardiac CTA. With all of the talk of cut backs on Medicare reimbursements in this area I find it hard to believe that this exam should be considered. CTAs of the Heart are becoming the industry standard for patients that are not experience acute MI symptoms. Those patients will always needs immediate action taken by a cardiologist in a Cathlab setting.The results the cardiovascular CT imaging community has been waiting for two years are in: Sixty-four-slice CT meets cardiac catheterization in the primary diagnosis of cardiovascular disease and disorders in all populations, according to results of the CorE 64 study announced Monday by Julie Miller, MD, lead investigator of the study and assistant professor of medicine at Johns Hopkins Hospital, Johns Hopkins University in Baltimore, Md.

3d medical record
2008-01-21 16:57:00 The idea is to have a rendered 3D representation of the anatomy of the patient, and to use that as a basis for the record. This is reported in IEEE Spectrum.Visualizing Electronic Health Record s With ?Google-Earth for the Body? By Robert N. CharetteJanuary 2008Andre Elisseeff leads a research team at IBM?s Zurich Research Lab that in September demonstrated a prototype system that will allow doctors to view their patients? electronic health record (eHR) using three-dimensional images of the human body. Called the Anatomic and Symbolic Mapper Engine, the system maps the information in a patient?s eHR to a 3-D image of the human body. A doctor first clicks the computer mouse on a particular part of the image, which triggers a search of the patient?s eHR to retrieve the relevant information. The patient?s information corresponding to that part of the image is then displayed, including text entries, lab results, and medical images, such as magnetic resource imaging.Elisseeff hopes that b...

Laser infared energy for stroke treatment
2008-01-21 16:20:00 Laser Light for Stroke Treatment Filed under: NeurologyPhotoThera, a company out of Carlsbad, California, is currently conducting clinical trials of their experimental laser system for the treatment of strokes. Using a near-infrared laser that is capable of reaching the brain through the scalp, it is thought that the light can help reinvigorate cells in the ischemic milieu.To prevent Quire's [Linda Quire, stroke patient at University of Wisconsin Hospital in Madison --ed.] penumbra from going over to the dark side, two things had to occur.First, the laser treatment would have to work. Although animal studies and limited human research suggest it might be effective, the treatment still is in the experimental stage and its value has yet to be proved.Second, Quire would have to get the actual laser treatment. Under the protocol of the clinical trial, half the patients get the treatment and half get a sham treatment. Neither the doctor nor the patients know who is getting treated.Essent...

very low field MRI may be better for tumors.
2008-01-21 16:01:00 PHOTO: VADIM ZOTEV/LOS ALAMOS NATIONAL LABORATORYHEAD SHOTS: Four slices of researcher Vadim Zotev?s head are the first medical images made with low-magnetic-field MRI.Researchers at Los Alamos National Laboratory have made what they say are the first images of a human brain using magnetic fields a hundred-thousandth the strength of conventional magnetic resonance imaging (MRI), paving the way for lower cost medical images that might be better at detecting tumors.Though the resolution is much lower than that in conventional MRIs, the images ?show we have a potential for pretty good results,? says Vadim Zotev, a researcher in Los Alamos?s applied modern physics group. (That?s his head in the images.)MRI works by subjecting the human body to a strong magnetic field, which causes the proton in the nucleus of each hydrogen atom in the body to line up along the magnetic field?s lines of force. An RF pulse briefly knocks the protons out of alignment. As they snap back into ... More About: Field
