Professional Radiologists Forum: IMAGING OF STROKE AND CEREBRAL ISCHEMIA
http://professionalradiologists.blogspot.com/2009/12/imaging-of-stroke-and-cerebral-ischemia.html
Wednesday, December 9, 2009. IMAGING OF STROKE AND CEREBRAL ISCHEMIA. Embolic strokes characteristically have a very abrupt onset. After a number of hours, there may be sudden improvement in symptoms as the embolus lyses and travels more distally. The source of the embolus is usually either the heart (patients with atrial fibrillation or previous myocardial infarction) or ulcerated plaques at the carotid bifurcation in the neck. PHYSIOLOGY, METABOLISM, AND PATHOLOGY. CT AND MR IMAGING. After 6-8 hours th...

Professional Radiologists Forum: BOSNIAC CLASSIFICATION OF RENAL CYSTS
http://professionalradiologists.blogspot.com/2009/10/bosniac-classification-of-renal-cysts.html
Wednesday, October 7, 2009. BOSNIAC CLASSIFICATION OF RENAL CYSTS. Renal cysts are very common, occurring in approximately 1/3 to ½ of adults over 50 years of age. The cysts are typically classified according the Bosniak criteria, as follows:. Have a thin or imperceptible wall, no septations, and is of fluid density. Still demonstrate no enhancement, but may have thin septa and high density (60 to 90 HU). They may demonstrate calcification or minimal irregularity. Radiologic overview of the diagnosis:.

Professional Radiologists Forum: HEAD TRAUMA
http://professionalradiologists.blogspot.com/2009/12/head-trauma.html
Wednesday, December 9, 2009. Patients with head trauma constitute a large percentage of the cases referred for neuroimaging. Initially, the role of MR in these patients was considered limited due to the time required for the examination, difficulty in using life-support and monitoring equipment within the scanning room and problems in imaging acute hemorrhage. While some of these problems still remain, MR has come to be used more frequently in these patients, particularly in the subacute period. Varying ...

Professional Radiologists Forum: August 2008
http://professionalradiologists.blogspot.com/2008_08_01_archive.html
Sunday, August 10, 2008. PHYSICS OF COLOR DOPPLER IMAGING. When the receiver is stationary the frequency of sound emitted (Fo) and that reflected(Fr) from the receiver are the same. When the receiver of the sound is moving the frequency of emitted sound (from the source) shows change. If the receiver is moving towards the source the waves get closer and net frequency is increased (positive change). If the receiver is moving away, the net frequency is decreased.(negative change). V= blood flow velocity.
