Magnetic resonance imaging of dural sinus thrombosis with resolution.

Cerebral venous thrombosis is difficult to diagnose clinically. Often, the presence of this disorder is not suspected, and, when it is, proof of its existence has in the past required cerebral angiography. The authors present a case of cerebral venous thrombosis diagnosed with magnetic resonance imaging (MRI). Complete resolution of the thrombus was also documented by MRI. To the authors' knowledge, the latter use of MRI has never been reported before. Previous cases of cerebral venous thrombosis are also reviewed. The authors believe that MRI probably will become the test of choice in the diagnosis of this disorder.

Peripheral facial nerve dysfunction: CT evaluation.

Peripheral facial nerve dysfunction may have a clinically apparent or occult cause. We reviewed the clinical and radiographic records of 36 patients with peripheral facial nerve dysfunction to obtain information on the location of the suspected lesion and the number, sequence, and type of radiographic evaluations performed. Inadequate clinical evaluations before computed tomography (CT) was done and unnecessary CT examinations were also noted. In those patients in whom the cause of peripheral facial nerve dysfunction is apparent, the clinical-radiographic workup is self-evident. When the cause of dysfunction is occult, however, a tailored CT examination should be done based on a thorough clinical evaluation. We have suggested a practical clinical and radiographic scheme to evaluate progressive peripheral facial dysfunction with no apparent cause. If this scheme is applied, unnecessary radiologic tests and delays in diagnosis and treatment may be avoided.

Evaluation of technetium-99m phosphate imaging for predicting skin ulcer healing.

We have developed criteria for radionuclide angiography to assess skin ulcer perfusion as an indicator of healing capacity. Twenty-six studies were performed on 21 consecutive patients with nonhealing ulcers of the lower leg; 20 mCi of technetium-99m phosphate was injected intravenously with immediate sequential scintillation camera imaging of the ulcer and surrounding area at 2 second intervals, followed by blood pool and delayed static images. Two radiologists without clinical bias graded the perfusion to the ulcer on the images as normal, increased, or reduced with respect to the opposite limb. Patients were either followed as outpatients for more than 10 days, as inpatients for at least 10 days, or both to determine whether ulcers showed clinical evidence of wound healing with optimal outpatient and in-hospital care. Of the 17 patients whose ulcers healed, imaging with technetium-99m phosphate predicted the outcome in 16. In nine patients the ulcers did not heal. This was correctly predicted by technetium-99m phosphate in eight of the patients. Overall, the sensitivity was 94 percent and the specificity was 89 percent. This technique appears to be a simple, reliable way to predict the microcirculatory adequacy for ulcer healing.
