Hammersmith Hospitals NHS Trust


CT fluoroscopy is a new real time imaging technique which allows greater control and accuracy for biopsy guidance using CT. Data will be presented from an initial 21 patients undergoing CT guided biopsy using a Siemens Plus 4 scanner with CARE Vision. Parameters to be reported include patient skin doses, operators' hand and eye doses and screening time. All doses were measured using TLDs. Comparisons will be made with other figures from the radiology literature. Comments on fluoroscopic technique will be made.
