[ 1 ] - A rare presentation of osteoid osteoma in a rib and unexpected \"double density sign\": A case report and review of literature
Osteoid osteoma (OO) is a relatively common skeletal neoplasm, frequently involves long bones. OO of rib is extremely rare, including 0.23-2% of OO cases. Most of them arose in posterior arc, frequently in its head or neck and might lead to painful scoliosis. Involvement of anterior aspect of a rib is extremely rare. Skeletal scintigraphy is highly sensitive for detection of OO. “Doubl...
[ 2 ] - Satisfaction of Medical Residents of Shahid Beheshti University of Medical Sciences from the training of Cross Sectional Anatomy and CT SCAN
BACKGROUND AND OBJECTIVE: Nuclear medicine specialty based on the imaging of various organ functions has progressed in recent years with the improvement of imaging techniques towards hybrid imaging requiring knowledge of cross sectional anatomy. On the other hand, with the passing of time, most of knowledge of anatomy has been forgotten. METHODS: This study was conducted in an experimental stud...
[ 3 ] - Comparison of “heart and lung volume absorbed dose” between electron and photon boost radiotherapy after breast conserving surgery
Background: Breast conserving surgery (BCS) followed by radiotherapy (RT) has been widely accepted as the standard treatment in early stages of invasive breast cancer. The standard technique of RT includes whole breast irradiation (WBI). Additional tumor bed boost irradiation has also an important role in the local tumor control. But there are various controversial delivery methods. The aim of ...
[ 4 ] - The truncation artifact in a skinny patient following myocardial perfusion SPECT
Myocardial perfusion SPECT is one of the most common imaging techniques performed in nuclear medicine departments. To avoid misleading interpretation, it is necessary to address the quality control and technical problems. The truncation artifact occurs when the patient size is large relative to the field of view of the camera, causing false perfusion defects in the LV myocardium, misinterpreted...
[ 5 ] - Massive hepatomegaly in 99mTc-octreotide scintigraphy: The value of 99mTc-sulfur colloid scan
99mTc-octreotide scintigraphy, performed during the following up a 58-year old man with neuroendocrine tumor demonstrated massive hepatomegaly demonstrating multiple areas of increased and decreased uptake. Due to severe hepatomegaly concurrence of any other abdominal soft tissue lesions could not be excluded. A 99mTc-sulfur colloid scan was done and thoroughly compared wi...
