The L/B ratios or lesion contrast of acoustic schwannomas at various fractional contrast medium doses was significantly higher compared with that of intraparenchymal lesions. Thus, the standard contrast medium dose may not be necessary for detection of acoustic schwannomas, and a fractional dose...
The results show that 1024 matrix MRI is technically feasible in clinically acceptable imaging time and offers advantage for high resolution imaging. Optimization of 1024 matrix and 3D FT GRASE imaging should improve the delineation of anatomic regions of interest.
Pituitary apoplexy almost invariably occurs following hemorrhage into a pituitary neoplasm. We report a case in which pituitary apoplexy occurred in the setting of, and probably secondary to, dissection of the internal carotid artery.
We conclude that in patients with lipoid pneumonia CT may demonstrate areas with low attenuation diagnostic of fat or areas with nonspecific low attenuation or soft tissue density.
In cases of periosteal chondrosarcomas in the foot MRI can play a significant role both in the characterization of the lesion and in planning surgical therapy.
Though cystic hepatic lesions may have features that help characterize them by noninvasive imaging modalities, these findings are often nonspecific and may be unable to establish the presence of malignancy. This is illustrated here by describing an epidermoid cyst of the liver containing...
Closed mouth off-sagittal imaging of the disk in the closed mouth position should be included prior to appliance placement to detect anterior displacements with very early recapture.
In the immunocompromised and chronically debilitated host, pulmonary nocardiosis should be included in differential diagnosis if chest CT shows consolidation with low attenuation areas with or without cavitation, multiple pulmonary nodules, pleural effusion, and chest wall extension.
We report a case of circumscribed intrapulmonary hematoma, in which MR findings were useful in establishing the diagnosis. It is usually easy to make a diagnosis of intrapulmonary hematoma using conventional methods, when clinical history of trauma and regression of the mass can be observed on...
