3.0 T diffusion tensor imaging and fiber tractography of the testes in nonobstructive azoospermia.

Purpose: To assess the role of 3.0 T Diffusion Tensor Imaging (DTI) and Fiber Tractography (FT) of the testes in the work-up of nonobstructive azoospermia (NOA).

Methods: This prospective study included consecutive NOA men and controls.

Diffusion tensor imaging and fiber tractography of the normal epididymis.

Purpose: To evaluate the feasibility of diffusion tensor imaging (DTI) and fiber tractography (FT) of the normal epididymis and to determine normative apparent diffusion coefficient (ADC) and fractional anisotropy (FA) values.

Methods: Twenty-eight healthy volunteers underwent MRI of the scrotum, including DTI on a 3.0 T system.

Complex cystic liver lesions: classification, diagnosis, and management.

Cystic liver disease has been increasingly reported in the literature, with a prevalence as high as 15-18%. Hepatic cysts are usually discovered incidentally, while their characterization and classification rely on improved imaging modalities. Complex cystic liver lesions comprise a wide variety of novel, re-introduced, and re-classified clinical entities.

The genitourinary system in ancient Greece: a historical perspective.

The Ancient Greeks were great innovators in all academic fields, including medicine. Hippocrates of Kos, the Father of Medicine, established many terms for the genitourinary (GU) system, such as nephros, urethra, urogenital, and adenocarcinoma. According to Hesiod's , Aphrodite, the goddess of love and beauty, was born off the coast of Kythera, from the foam produced by Uranus's genitals, after his son Cronus had thrown them into to the sea.
