Medical imaging of the parathyroid glands.

In patients with hyperparathyroidism, the detection and localization of parathyroid lesions can aid the surgeon preoperatively and prior to re-exploration if the initial surgery fails. Computed tomography, ultrasound, and radionuclide scintigraphy are currently most commonly used to evaluate the parathyroid glands in patients with hyperparathyroidism. This article will review the experience, techniques, and advantages of these respective imaging modalities in the evaluation of parathyroid lesions.

Multiple myeloma with unusual intracranial manifestations.

We report a unique case of meningeal involvement of multiple myeloma in a 49-year-old man. The patient developed weakness late in the course of his disease, and a computed tomographic scan revealed intracranial masses. At postmortem examination these tumors were the predominant extramedullary manifestation of the patient's anaplastic myeloma. To our knowledge this is the first case of intracranial myeloma composed of multiple, discrete masses.

MR fat suppression technique in the evaluation of normal structures of the knee.

The chopper fat suppression (CFS) pulse sequence, which is a phase sensitive implementation of the Dixon fat suppression method and the spin echo (SE) pulse sequence, was used in the evaluation of anatomic structures of the normal knee using 48 sets of imaging sequences in six volunteers using a repetition time/echo time combination of 1,500/30, 60 ms. A demonstration of the CFS technique in 10 patients with suspected knee pathology is also presented. A semiquantitative grading scale was established to rate anatomic visualization and used to compare CFS and SE pulse sequence techniques. The results in normal subjects demonstrate that hyaline cartilage is significantly better visualized by fat suppression pulse sequence than by conventional SE pulse sequence in the coronal and sagittal planes of imaging (p less than 0.001). The preliminary results from patients studies suggest that CFS imaging may be useful in the evaluation of meniscal tears, in the differentiation of hyaline cartilage from joint fluid, and in the detection of both soft tissue and bone injuries.
