PURPOSE To determine whether color Doppler sonography can be a sensitive alternative to screening arteriography for identifying arterial injury in patients with penetrating traumatic neck injuries. METHODS Fifty-two patients admitted to our trauma center with penetrating neck injuries (gunshot wounds and lacerations) were examined prospectively with color(More)
PURPOSE To determine the MR and CT findings that characterize acute spinal subdural hematoma (ASSH). METHODS The MR, CT, and clinical findings in three patients with surgically proved ASSH were reviewed and also correlated with the postmortem MR, CT, and cryomicrotome findings in three other patients, two with ASSH and one with an acute spinal epidural(More)
Assessment of suspected cervical spine injuries remains a major debate in trauma care. It is generally accepted that many fractures are missed or incompletely shown at radiography, mainly because of suboptimal studies obtained in obtunded, uncooperative trauma victims. In a series of 88 severely traumatized patients, the authors retrospectively determined(More)
PURPOSE To describe the MR manifestations and temporal course of wallerian degeneration that occurs above and below a spinal cord injury, and to compare the MR findings with postmortem histopathology. METHOD Twenty-four postmortem spinal cords from patients with cervical (n = 14), thoracic (n = 6), and lumbar (n = 4) cord injuries were studied with axial(More)
OBJECTIVE Eight patients with traumatic occlusion of the renal artery were retrospectively reviewed to assess the diagnostic contribution of helical CT and to determine whether the information it provides can replace angiographic data in patient evaluations. MATERIALS AND METHODS We reviewed the medical records and imaging studies of eight patients with(More)
This study was performed to evaluate helical computed tomography (HCT) as the primary method of initial cervical spine assessment in multiple trauma victims. Prospective evaluation of the cervical spine using HCT and plain film radiography (PFR) was performed in 800 patients with suspected multisystem injuries. With HCT, an average of 32 slices were(More)
A right-sided aorta with an isolated left subclavian and left common carotid artery is a rare arch defect. We are presenting the case of a 56-year-old woman who had initially presented with headache and 3 episodes of right-sided facial and extremity numbness. A presumptive diagnosis of transient ischemic attack prompted imaging studies where a computer(More)
Ten patients with subhepatic fluid collections complicating laparoscopic Cholecystectomy were successfully treated by interventional radiological procedures. The series included five abscesses, three hematomas, one biloma, and one serous collection. Abdominal pain or fever developed from 3 to 21 days after the laparoscopic intervention. All patients were(More)
