OBJECTIVE The purpose of this study was to evaluate the sensitivity and specificity of seven CT signs in the diagnosis of internal hernia after laparoscopic Roux-en-Y gastric bypass. MATERIALS AND METHODS With institutional review board approval, the CT scans of 18 patients (17 women, one man) with surgically proven internal hernia after laparoscopic(More)
PURPOSE To evaluate the frequency of detection of trauma-induced adrenal gland hematoma in current practice by using computed tomography (CT) and to correlate presence of adrenal hematoma with quantitative clinical indicators of injury severity. MATERIALS AND METHODS The radiology information system and the trauma registry were searched for cases of(More)
Trauma is a major cause of death and disability and renal injuries occur in up to 10% of patients with significant blunt abdominal trauma. Patients with penetrating trauma and hematuria, blunt trauma with shock and hematuria, or gross hematuria warrant imaging of the urinary tract specifically and CT is the preferred modality. If there is significant(More)
PURPOSE To evaluate the ability of magnetic resonance (MR) imaging to depict solid debris within pancreatic collections prior to intervention and to help assess drainability, as well as to compare MR findings with those obtained at computed tomography (CT) and ultrasound (US). MATERIALS AND METHODS Nineteen collections in 18 patients were evaluated with(More)
Adrenal pathology may be discussed based on hormonal functionality of the adrenals, appearances on imaging modality, or pathological determination. There are three main categories of adrenal function. Hyperfunctional states include Conn's or Cushing's syndrome. Lesions with normal function may be detected incidentally. Hypofunctional states may occur from(More)
PURPOSE To determine whether ultrasound (US) is a sensitive follow-up method after placement of a carotid artery stent for the detection of significant stenosis, occlusion, and other complications at early and intermediate follow-up. MATERIALS AND METHODS Doppler US examinations were performed after stent placement in 170 carotid arteries in 119 patients(More)
Calcium channel antagonists can be quite toxic. In the management of poisoning, early recognition is critical. Calcium channel antagonists are frequently prescribed, and the potential for serious morbidity and mortality with overdosage is significant. Ingestion of these agents should be suspected in any patient who presents in an overdose situation with(More)
OBJECTIVE The purpose of our study was to determine the prevalence, distribution, and clinical significance of pancreatic ductal changes due to pancreatitis on ERCP in patients with pancreas divisum. MATERIALS AND METHODS From January 1993 through December 1997, 1714 patients underwent 2469 ERCP studies. Ninety-four patients (5.5%) had pancreas divisum.(More)
Soft tissue sarcoma (STS) management requires accurate tumor imaging for staging, treatment planning, and clinical follow-up. Careful preoperative planning may prevent poor primary resections that place the patient at risk for more operations, local recurrence, and worse survival. Although MRI may be preferred for extremity STS, contrast-enhanced CT is an(More)
