Imaging of sacral fractures.

The article discusses traumatic, insufficiency and pathological sacral fractures. Special attention is paid to the biomechanics and subsequent classification of traumatic sacral fractures.

Radiological percutaneous gastrostomy.

Long-term gastrostomy tubes have a widely accepted role in providing nutritional support. Traditionally, they have been placed by surgeons and by endoscopists. In the last decade, radiologists have come to play a major role in the placement of gastrostomy and gastrojejunostomy devices, and can usually do so as effectively and at lesser expense. A technique for placement is outlined, with a discussion of patient selection and complications. A review of the literature is provided.

Ct findings in blunt renal trauma.

Computed tomography (CT) can provide essential anatomic and physiologic information required to determine management of intraabdominal and retroperitoneal injuries sustained during blunt abdominal trauma. It can help in evaluation of the type and severity of parenchymal injury, the extent of perirenal hemorrhage and parenchymal devascularization, and the presence of urinary extravasation. CT can help confirm the presence of major injuries to the vascular pedicle and depict occult renal pathologic conditions. Principal indications for the use of CT in the evaluation of blunt renal trauma include (a) the presence of gross hematuria, (b) microscopic hematuria associated with shock (systolic blood pressure <90 mm Hg), and (c) microscopic hematuria associated with a positive result of diagnostic peritoneal lavage. The majority of renal injuries sustained during blunt abdominal trauma are contusions and minor parenchymal lacerations amenable to nonoperative management. Deep parenchymal lacerations, urinary extravasation, and mild to moderate degrees of parenchymal devascularization may also be treated conservatively. Radiologists should look for coexisting renal lesions such as tumors and traumatic false aneurysms that may alter management.

MR imaging of brachial plexopathy in breast cancer patients without palpable recurrence.

OBJECTIVE: To investigate the role of MR imaging in detecting brachial plexus (BP) abnormalities in breast cancer patients with plexopathy but without palpable masses. DESIGN: MR imaging of the BP was performed on 26 breast cancer patients with brachial plexopathy without palpable regional masses, using 0.5 T and 1.5 T imaging systems. Findings were correlated with the clinical diagnoses. PATIENTS: Twenty-six patients with brachial plexopathy and history of breast cancer were enrolled in the study. All patients presented with plexopathy symptoms. Fourteen patients were positive and 12 patients were indeterminate for BP metastasis according to clinical criteria. RESULTS AND CONCLUSION: MR imaging demonstrated masses involving the BP representing metastases in two patients. Nine patients had other regional abnormalities with a normal brachial plexus. It is concluded that MR imaging is useful in the assessment and direction of therapy of brachial plexopathy in breast cancer patients by detecting both metastases to the BP as well as other abnormalities, unrelated to the BP, which may explain the patient's symptoms.
