Evaluation of testicular vein anatomy with multidetector computed tomography.
Summary of "Evaluation of testicular vein anatomy with multidetector computed tomography."
PURPOSE:
We aimed to evaluate the normal anatomy and variations of testicular veins by multidetector CT (MDCT). MATERIALS AND
METHODS:
This prospective study included 101 male patients who underwent abdominal CT for various clinical indications. Mean age of patients was 53 years. Images were obtained by dual source 64-slice MDCT (n = 61) and 64-MDCT (n = 41). Images were analyzed using 1 mm thick slices on a dedicated workstation. The number of testicular veins, drainage site and diameter of proximal, mid and distal testicular veins were recorded.
RESULTS:
Testicular veins were visualized in all patients. There were single right testicular vein in 99 (98%) patients and 2 (2%) patients had duplicated right testicular veins (total 103 veins). Right testicular vein drained into inferior vena cava in 88 (87.1%) patients and right renal vein in 13 (12.9%) patients. One of duplicated right testicular veins drained into inferior vena cava and other paired drained into right renal vein and inferior vena cava separately. There were single left testicular vein in 88 (87.1%) patients and 13 (12.9%) patients had duplicated veins (total 14 veins). All left testicular veins drained into left renal vein.
CONCLUSION:
64-MDCT enables evaluation of testicular veins in all patients. Right and left testicular veins are usually single, but can be duplicated more commonly.

Medical and Biotech [MESH] Definitions
Anatomy, Cross-sectional
Descriptive anatomy based on three-dimensional imaging (IMAGING, THREE-DIMENSIONAL) of the body, organs, and structures using a series of computer multiplane sections, displayed by transverse, coronal, and sagittal analyses. It is essential to accurate interpretation by the radiologist of such techniques as ultrasonic diagnosis, MAGNETIC RESONANCE IMAGING, and computed tomography (TOMOGRAPHY, X-RAY COMPUTED). (From Lane & Sharfaei, Modern Sectional Anatomy, 1992, Preface)
Tomography, Spiral Computed
Computed tomography where there is continuous X-ray exposure to the patient while being transported in a spiral or helical pattern through the beam of irradiation. This provides improved three-dimensional contrast and spatial resolution compared to conventional computed tomography, where data is obtained and computed from individual sequential exposures.
Cone-beam Computed Tomography
Computed tomography modalities which use a cone or pyramid-shaped beam of radiation.
Tomography, X-ray Computed
Tomography using x-ray transmission and a computer algorithm to reconstruct the image.
Tomography, Emission-computed
Tomography using radioactive emissions from injected RADIONUCLIDES and computer ALGORITHMS to reconstruct an image.
