Quantitative radiology: automated CT liver volumetry compared with interactive volumetry and manual volumetry.
OBJECTIVE The purpose of this study was to evaluate automated CT volumetry in the assessment of living-donor livers for transplant and to compare this technique with software-aided interactive volumetry and manual volumetry. MATERIALS AND METHODS Hepatic CT scans of 18 consecutively registered prospective liver donors were obtained under a liver transplant protocol. Automated liver volumetry ...
متن کاملInfluences in CT scan lung nodule volumetry.
Lung nodule measurements made with CT imaging are used in clinical practice to assess size changes estimated from serial scans obtained over time to predict the likelihood of malignancy and to monitor the tumor response to treatment. 2 Size measurements need to be accurate and consistent to enable the assessment of nodule changes in a short time interval. Th e precision and accuracy of volume m...
متن کاملEvaluation of postoperative lymphocele according to amounts and symptoms by using 3-dimensional CT volumetry in kidney transplant recipients
PURPOSE To analyze the risk factors for postoperative lymphocele, for predicting and preventing complications. METHODS We evaluated 92 kidney transplant recipients with multidetector CT (MDCT) at 1-month posttransplantation. From admission and 1-month postoperative records, data including diabetes, dialysis type, immunosuppressant use, steroid pulse therapy, and transplantation side were coll...
متن کاملPancreatic mucinous cystic neoplasm size using CT volumetry, spherical and ellipsoid formulas: validation study.
CONTEXT The accuracy for determining pancreatic cyst volume with commonly used spherical and ellipsoid methods is unknown. The role of CT volumetry in volumetric assessment of pancreatic cysts needs to be explored. OBJECTIVES To compare volumes of the pancreatic cysts by CT volumetry, spherical and ellipsoid methods and determine their accuracy by correlating with actual volume as determined ...
متن کاملAspects of computer-aided detection (CAD) and volumetry of pulmonary nodules using multislice CT.
With the superb spatial resolution of modern multislice CT scanners and their ability to complete a thoracic scan within one breath-hold, software algorithms for computer-aided detection (CAD) of pulmonary nodules are now reaching high sensitivity levels at moderate false positive rates. A number of pilot studies have shown that CAD modules can successfully find overlooked pulmonary nodules and...
