Ancient Schwannoma as an exceptional thoracic spinal tumor: A case report.

Schwannomas are mostly benign tumors arising from the nerve sheath. These tumors can be found anywhere in the body. Depending on their locations, they may cause compressive symptoms as well as cosmetic or functional defects.

The ability and utility of diffusion-weighted magnetic resonance imaging with different 'b' values in the differentiation of benign from malignant lung lesions.

Purpose: To evaluate the ability and the utility of diffusion-weighted magnetic resonance imaging (MRI) with different 'b' values to visualise benign and malignant lung lesions, and to determine which 'b' value (b = 300, 500, or 1000 s/mm) was most useful in differentiating benign from malignant lung lesions.

Material And Methods: A total of 100 patients (28 women, 72 men; mean age = 57.19 ± 13.

Usefulness of Apparent Diffusion Coefficient of Diffusion-Weighted Imaging for Differential Diagnosis of Primary Solid and Cystic Renal Masses.

Background: To evaluate the value of diffusion-weighted imaging (DWI) for distinguishing between benign and malignant renal masses.

Material/methods: Seventy-five patients with 75 unilateral renal lesions were included, and 75 normal contralateral kidneys served as controls. The lesions were categorized into four groups as malignant cystic, malignant solid, benign cystic and benign solid.
