PURPOSE To quantify prostate motion during a radiation therapy treatment using cine-magnetic resonance imaging (cine-MRI) for time frames comparable to that expected in an image-guided radiation therapy treatment session (20-30 min). MATERIALS AND METHODS Six patients undergoing radiation therapy for prostate cancer were imaged on 3 days, over the course(More)
OBJECTIVE To determine the accuracy of magnetic resonance spectroscopy (MRS), perfusion MR imaging (MRP), or volume modeling in distinguishing tumor progression from radiation injury following radiotherapy for brain metastasis. METHODS Twenty-six patients with 33 intra-axial metastatic lesions who underwent MRS (n=41) with or without MRP (n=32) after(More)
Since the inception of radiosurgery, the management of brain metastases has become a common problem for neurosurgeons. Although the use of stereotactic radiosurgery and/or whole brain radiation therapy serves to control the majority of disease burden, patients who survive longer than 6–8 months sometimes face the problem of symptomatic radiographically(More)
OBJECTIVE To determine if T1ρ magnetic resonance imaging (T1ρ MRI) could assess early articular cartilage changes in knees of asymptomatic female collegiate athletes. It was hypothesized that impact cohort would demonstrate greater changes than nonimpact cohort. DESIGN An institutional review board-approved prospective cohort study. Blinded MRI analyses.(More)
Hypertriglyceridemia is a form of dyslipidemia that can lead to the development of pancreatitis. In this form of pancreatitis the serum pancreatic enzymes may be normal or mildly elevated. In addition to the regular treatment of pancreatitis of any etiology, plasmapheresis has been shown to improve the symptoms, laboratory findings, and outcome of(More)
OBJECTIVE Our aim was to determine the efficacy of laparoscopic cholecystectomy in symptomatic patients with ultrasound negative and abnormal gallbladder ejection fractions; Patients with gallbladder ejection fractions less than 35% on hepatobiliary scan were offered laparoscopic cholecystectomy. METHODS Between January 1995 and January 2001, 1564(More)
BACKGROUND Abdominal impalement injuries are usually associated with visceral and vascular injury, causing significant morbidity and mortality. The management of these injuries poses specific challenges in prehospital care, transport, and management strategies. OBJECTIVE We report a case of transabdominal impalement with no injury to intra-abdominal(More)
In treating trigonocephaly, the value of direct surgical correction of orbital hypotelorism is controversial. In many cases of hypotelorism, the distance between the orbits increases over time after traditional fronto-orbital advancement. Still, more severe hypotelorism is not fully corrected and may benefit from a more definitive surgical intervention. We(More)
We describe an 11-month-old boy with an unusually large presternal mass present since birth. The large size, fluctuant properties, transillumination, compressibility, and imaging of this lesion were characteristic of a lymphatic malformation. Although four treatments with sclerotherapy markedly reduced its size, it was not until definitive treatment with(More)
