Diagnostic performance of real-time robotic arm-assisted 18F-FDG PET/CT-guided percutaneous biopsy in metabolically active abdominal and pelvic lesions

Abstract

Percutaneous biopsy of metabolically active abdominal and pelvic lesions with ARA assistance is a technically feasible, safe and accurate method for pathological diagnosis with high diagnostic performance. PET-guided biopsy is highly practical and useful in patients, especially in those with a previous inconclusive biopsy.

“…Another practical application of our trimodal compounds might be their use in robotic surgery. Identification of the exact site of the lesion is greatly enhanced if ICG fluorescence is combined with a radioactive signal from the same probe [33,34]. In particular, the Da Vinci robot can be equipped with a fluorescence imager and radioactivity detection system, thus avoiding problems related to the use of halogen lamps, as occurs during open surgery.…”

Evaluation of radiation exposure to the patients undergoing positron emission tomography/computed tomography-guided biopsies

“…[ 3 8 ] PET/CT-guided biopsies can be done either using an automated robotic arm that plans orientation of needle trajectory or with the help of fiducial markers using a helical CT or under CT fluoroscopy. [ 9 10 11 ] In either case, the positioning of the needle to the target lesion is checked by acquiring low-dose CT images (check CT scan). A robotic arm was used to target the lesions in a single pass and minimizes the need for multiple check CT scans.…”

“…A robotic arm was used to target the lesions in a single pass and minimizes the need for multiple check CT scans. [ 10 11 12 ] It reduces the radiation exposure to the personnel performing biopsies and the patient undergoing the procedure. [ 13 14 15 ] The number of check CT scan varies depending upon the size of the lesion, its depth, and any vital structure in the vicinity of the lesion.…”
