Percutaneous abdominal and pelvic interventional procedures using CT fluoroscopy guidance.

Abstract

OBJECTIVE.The purpose of our study was to assess the use of low-milliamperage CT

Percutaneous drainage of abdominal fluids using available materials: University of Benin teaching hospital experience

“…CT does not have this limitation, but because of its radiation dose, it is not used as "first-line" interventional equipment for PD. However CT or CT fluoroscopy may be used in such instances where ultrasound imaging is limited [8,11]. Magnetic resonance imaging can image fluid collection including abscesses, but it remains relatively unavailable in several Nigerian health institutions.…”

Percutaneous cryoablation of renal masses under CT fluoroscopy: radiation doses to the patient and interventionalist

“…Computed tomographic (CT) fluoroscopy is well suited for the rapid targeting, localization, and placement of needles and probes during percutaneous interventional procedures [1]. Percutaneous thermal ablation has demonstrated an increasingly prominent role as a minimally invasive treatment for renal tumors [2][3][4].…”

“…A variety of techniques may be utilized by the interventionalist performing the CT-guided fluoroscopic procedure, including alterations in patient positioning, CT gantry angulation, intravenous contrast material administration, multi-probe ablation, and hydrodissection of adjacent structures [1,10]. The techniques described above may all result in increased fluoroscopy time and radiation dose required to perform tumor ablation.…”

CT fluoroscopic guidance for percutaneous needle placement into abdominopelvic lesions with difficult access routes

“…Biopsy or aspiration was diagnostic in 10 patients. Needle advancement was not attempted in two patients.Conclusion: CTF appears to be a valuable tool to dynamically assist percutaneous needle placement into lesions that may be considered difficult with standard CT assistance.Computed tomography fluoroscopy (CTF) has been used for a variety of abdominal and pelvic procedures including biopsy, fluid collection aspiration or drainage, percutaneous ethanol ablation, sympathectomy, preoperative hepatic tumor localization, and ethanol injection of hepatocellular carcinoma [1][2][3][4][5][6]. Several studies have suggested that using CTF assistance for percutaneous procedures of the abdomen and pelvis results in increased needle accuracy and decreased procedure time compared with conventional computed tomography (CT) guidance [5,[7][8].…”

“…gested that using CTF assistance for percutaneous procedures of the abdomen and pelvis results in increased needle accuracy and decreased procedure time compared with conventional computed tomography (CT) guidance [5,[7][8]. Its usefulness in performing procedures that would be difficult to perform with conventional CT guidance, however, has yet to be determined.…”
