Background. Ketamine has been reported to have efficacy as an antidepressant in several studies of treatment-resistant depression. In this study, we investigate whether an acute administration of ketamine leads to reductions in the functional connectivity of subgenual anterior cingulate cortex (sgACC) with other brain regions. Methods. Thirteen right-handed(More)
OBJECTIVE We describe the CT findings of medial transfer of a sartorius muscle flap, which is done to protect the femoral blood vessels after radical inguinal lymphadenectomy for cancer or surgical debridement of infected femoral vascular grafts. MATERIALS AND METHODS We reviewed the appearances and initial interpretations of 33 CT studies in 17 patients(More)
OBJECTIVE Despite the increasing success of pancreatic transplantation for diabetes, rejection remains the most common cause of graft loss. The purpose of this study was to correlate gray-scale sonographic morphology and Doppler resistive index (RI) with acute pancreatic transplant rejection as determined by percutaneous, sonographically guided biopsy of(More)
BACKGROUND Cryosurgery can be employed in patients with unresectable hepatic metastases when the tumor size and the number of metastases are limited. However, local recurrence can result from incomplete ablation. We proposed a trial of complete cytoablation with a combined approach of cryosurgery and hepatic resection for patients with bilobar hepatic(More)
OBJECTIVE Laparoscopic techniques are evolving for a wide range of surgical procedures outside the biliary tree. We describe the CT findings of important complications detected after nonbiliary laparoscopic gastrointestinal surgery and the role of CT in their management. MATERIALS AND METHODS Over a 3-year period, 209 patients had nonbiliary(More)
OBJECTIVE Maintaining high standards in a large CT imaging department with multiple scanners, a large technical and clerical staff, and a rotating staff of radiologists is an ongoing challenge. We undertook a project to design and implement a simple, rapidly performed computer-assisted system of quality assurance (QA) for use in abdominal CT. In our(More)
PURPOSE To determine the value of magnetic resonance (MR) angiography and MR imaging with dynamic gadopentetate dimeglumine-enhanced gradient-echo (Gd-GRE) sequences in detection of vascular complications of pancreatic transplantation. MATERIALS AND METHODS Three radiologists evaluated findings of 32 MR examinations in 20 adult patients who underwent(More)
