Magnetic resonance imaging for evaluating neurogenic dysphagia
Dysphagia due to CNS pathology usually stems from one of two patterns of disease: (1) bilateral corticobulbar tract dysfunction (“pseudobulbar palsy”) or (2) pontomedullary dysfunction (“bulbar palsy”). Comput...

Omental teratoma in an adult: A case report
We recently experienced an omental teratoma in a 34-year-old woman. Ultrasonography (US) revealed a large mass of mixed echogenicity, occupying the entire lower abdomen. Computed tomography showed an inhomogen...

Computed tomographic findings of ruptured hepatic malignancy
Massive hemorrhage from ruptured hepatocellular carcinoma is uncommon. We report our experience in three cases of ruptured hepatocellular carcinoma diagnosed by computed tomography (CT). CT was useful in detec...

Gating provides improved accuracy for differentiating artifacts from true lesions in equivocal fixed defects on technetium 99m tetrofosmin perfusion SPECT
Because equivocal fixed perfusion defects on single photon emission computed tomography (SPECT) often cause a diagnostic dilemma in patients with suspected coronary artery disease (CAD), we used receiver-opera...

123I-MIBG myocardial scintigraphy as a noninvasive screen for the diagnosis of coronary artery spasm
It has been suggested that the sympathetic nervous system might play an important role in the development of coronary artery spasm. However, no cardiac imaging modality has been able to demonstrate abnormal sy...

Iodine-123 MIBG imaging before treatment of heart failure with carvedilol to predict improvement of left ventricular function and exercise capacity
We examined whether cardiac sympathetic imaging with iodine-123 metaiodobenzylguanidine (MIBG) would predict improvement of left ventricular (LV) function and exercise capacity in patients with heart failure a...

Dipyridamole myocardial SPECT with low heart rate response indicates cardiac autonomic dysfunction in patients with diabetes
Because dipyridamole is used to assess heart rate (HR) variability, we investigated whether a low HR response during dipyridamole single photon emission computed tomography (SPECT) in patients with diabetes in...

Glomus tumor of the stomach: CT findings
We present the radiologic findings of gastric glomus tumors in two patients, in whom upper gastrointestinal series and computed tomography (CT) were primarily used for diagnosis. The diagnosis was surgically c...

Segmentation by evolution for visualization of the lower extremity of the visible man
Medical image segmentation is the crucial process for three-dimensional (3D) modeling. Many studies have claimed to suggest more accurate ways of segmentation. However, such research seems to have the drawback...
