OBJECTIVE The purpose of this study was to determine the accuracy of CT angiography using a multidetector scanner in the evaluation of patients with peripheral vascular disease. SUBJECTS AND METHODS Eighteen patients with peripheral vascular disease who were referred for elective digital subtraction angiography (DSA) also underwent CT angiography. We(More)
OBJECTIVES The purpose of this study was to assess the physiologic significance of coronary artery lesions with an integrated single-photon emission computed tomography (SPECT) and computed tomography coronary angiography (CTCA) device. BACKGROUND Myocardial perfusion imaging (MPI) with SPECT is of value for assessing the physiologic significance of(More)
OBJECTIVE The objective of our study was to evaluate the accuracy of color Doppler sonography and contrast-enhanced MDCT in the diagnosis of acute appendicitis in adults and their utility as a triage tool in lower abdominal pain. MATERIALS AND METHODS We reviewed the medical records of 420 consecutive adult patients, 271 women and 149 men, 18 years old or(More)
OBJECTIVE Somatostatin receptor scintigraphy (SRS) of neuroendocrine (NE) tumours is often challenging because of minute lesion size and poor anatomic delineation. This study evaluates the impact of sequentially performed single-photon emission computed tomography (SPECT)/CT fusion on SRS study interpretation and clinical management of these tumours. (More)
OBJECTIVES To evaluate feasibility and accuracy of a fully automatic algorithm (FAA) for calculating left ventricular volumes and ejection fraction (LVEF) from multidetector computed tomography (MDCT) studies versus a previously validated method based on Simpson's method serving as our reference standard (RS), and left ventriculography (LVG), in patients(More)
Pneumatic reduction of intussusception under fluoroscopic guidance is a routine procedure. The unsedated child may resist the procedure, which may lengthen its duration and increase the radiation dose. We use deep sedation during the procedure to overcome these difficulties. The purpose of this study was to summarize our experience with deep sedation during(More)
UNLABELLED The present study evaluated the role of SPECT/CT as an adjunct to (67)Ga (GS) or (111)In-labeled white blood cell (WBC) scintigraphy for diagnosis or localization of infection. METHODS Eighty-two patients (56 male and 26 female; mean age, 62 y) assessed for known or suspected infectious processes underwent 88 SPECT/CT studies. Forty-seven(More)
The case of a mildly symptomatic 43-year-old man with evidence of reversible inferior wall ischemia by radioisotope stress testing is described. Invasive catheterization showed abnormal connections between the coronary arteries and the pulmonary circulation. Multidetector computed tomography elucidated the previously undescribed finding of a posterior(More)
UNLABELLED Graft infection after prosthetic vascular reconstruction is an uncommon but severe complication. The clinical presentation is often subtle and nonspecific and may occur long after surgery. Although defining a prosthetic vascular graft infection can be difficult, early diagnosis and treatment are important because of the relatively high rates of(More)
