OBJECTIVE To determine the clinical and helical CT findings in patients with skeletal muscle metastases from carcinoma, we reviewed the cases of 15 consecutive patients who had muscle metastases diagnosed by contrast-enhanced helical CT. MATERIALS AND METHODS Between February 1992 and August 1997, 15 patients (30 lesions) had metastatic disease to muscle(More)
OBJECTIVE In our multi center trial we compared the potentials of biphasic contrast-enhanced computed tomography (CT) and a novel tissue-specific magnetic resonance imaging (MRI) contrast agent gadoxetic acid disodium in liver lesion characterization. METHODS A total of 176 patients with 252 liver lesions were analyzed. There were 104 malignant and 148(More)
OBJECTIVE The objective of this study was to systematically review the use of MRI for the evaluation of deployment characteristics of vaginal microbicides and to understand the relationship of gel spread with potential influencing factors. METHODS Data from four clinical trials that used MRI to assess the deployment of a vaginal gel were combined. A(More)
Spiral computed tomography (CT) is a powerful modality for evaluation of the musculoskeletal system, particularly when coupled with real-time, volume-rendering reconstruction techniques. Including volume-rendered spiral CT in routine musculoskeletal imaging protocols can change management in a significant number of cases. In cases of trauma, subtle(More)
BACKGROUND Vaginal anatomy has been poorly studied. This study aimed to measure baseline dimensions of the undistended vagina of women of reproductive age. METHODS We combined baseline information collected from five clinical trials using magnetic resonance imaging (MRI) to quantify distribution of a vaginal gel. Seventy-seven MRI scans were performed on(More)
MR imaging has many advantages over other modalities in the detection and staging of renal neoplasms, because of its intrinsic high soft tissue contrast, direct multiplanar imaging capabilities, and the availability of a non-nephrotoxic, renally excreted contrast agent. The ongoing refinement of breath-hold imaging sequences will probably broaden the use of(More)
This was a blinded crossover study to determine the in vivo distribution of 2.5 and 3.5 mL of 6% cellulose sulfate gel. This potential vaginal microbicide was mixed with dilute gadolinium chelate and inserted into the vagina. Magnetic resonance imaging was performed at baseline and repeated after 5, 20, 35 and 50 min with subjects either resting or(More)
Behçet's disease is an idiopathic, recurrent multisystem syndrome characterized by oral aphthous ulcers, genital ulcers, and ocular inflammation. Small bowel involvement may occur in 1% of patients with aphthous ulceration which may mimic Crohn's disease. We report a case of a patient with Behçet's disease with small bowel pathology which simulated a mass(More)
