Abstract
The aim of this study was to identify the role of Multidetector CT in evaluation of ovarian veins in normal and abnormal states.
A NCCT scan was taken followed by IV contrast administration. Nonionic Optiray (Ioversol 64%, tyco Healthcare, Mallinckrodt, USA) 300mg Iodine/ml intravenous contrast material was used. Adult dose was 1-2mls/kg (maximum 150 mls) while pediatric dose was 1-1.5ml/kg. Administration was done at a flow rate of 2-5 ml/s depending on the indication of the examination and condition of the patient Scanning was initiated after a 18-25 sec for arterial phase, followed by repeated scanning with 60-70 sec delay for obtaining the venous phase (at which the ovarian veins are highlighted and is considered the best timing for their evaluation) this was followed by the delayed venous equilibrium phase.
The examinations were done using Siemens 64 slices (Somatom, Germany), Philips 16 slices and Philips 64 slices (Philips healthcare. Best, Netherlands) MDCT scanners. Scanning parameters were: 200 mAs, 140 KVP, tube rotation time of 1.0 s/rot., 2.0 mm slice thickness and 1.5 mm reconstruction interval for Philips 16 slices MDCT, while for Siemens 64 they were: 125 mAs, 130 KVP, tube rotation time of 1.19 s/rot, 1.5mm slice thickness and 1.5 mm reconstruction interval and 64 Philips: 30mAs, 140kvp, tube rotation time of 1.25s and slice thickness of 2.0mm.
Thin slice acquisition and multiplanar capability allowed accurate identification and tracking of both ovarian veins on all patients on both sides from their origin to termination and determination of their normal or pathological states as well other abdomino-pelvic disorders.
During the study period a total of five hundred and ten (510) patients were included in the study from female patients who were referred to radiology departments. They were put into different categories depending on age (range 1-85 years) clinical presentation/indication for MDCT, primary diagnosis and the pathologies of OV.
Most of the 231/510 (45.29%) studied patients with OV abnormalities were in their 5th and 6th decades. The least of examined patents with OV pathology were found in the extremes of ages. About 39 % of patients included in this study were on follow up due to malignancy, either before or after management. (Hepatocellular carcinoma 20, Gastro-intestinal 19, breast cancer 16, genito-urinary 16, lymphomas 13, four pancreatic cancer, lung cancer-one, and biliary cancer-cholangiocarcinoma in one case). Abdominal pain formed a significant number (82).
