multiple percutaneous drainage procedures may provide a rational therapeutic alternative. We report a patient with symptomatic syringomyelia involving the thoracic spine, which was managed by repeated CT- guided percutaneous aspiration procedures. CASE REPORT. A 70-year-old female presented a 3-month history
What is CT Guided Aspiration/Drainage? A CT Guided Aspiration/Drainage is an interventional procedure which involves the insertion of a needle into the body in order to remove fluid from an abnormal collection. Preparation. Please avoid eating solid food and drinking liquids other than water for 6-8 hours prior to the
The technique is largely the same as for ultrasound-guided percutaneous drainage procedures, with either a single step or multistep technique, although the latter is more commonly used in CT. A two- or three-part access needle is used to enter the abscess/collection, followed by the use of a stiff wire and serial dilators,
AJR Am J Roentgenol. 1982 Dec;139(6):1111-5. Utility of CT-guided abdominal aspiration procedures. Sundaram M, Wolverson MK, Heiberg E, Pilla T, Vas WG, Shields JB. Over 200 consecutive diagnostic needle aspiration procedures of the abdomen were performed under computed tomographic (CT) guidance.
CT-guided procedures were attempted in 103 patients suspected of having abscesses. CT-guided procedures were performed for diagnostic specimens in 70 patients; they were successful in 30 of 34 sterile collections and 33 of 36 abscesses. In another 33 patients, diagnostic aspiration was performed and percutaneous
What is a CT Drainage/Aspiration? A drainage/aspiration is a test in which CAT scan images allow the Radiologist (x-ray doctor) to insert a needle into an abnormal fluid collection in the body. The needle/catheter is You MAY be given sedation during your procedure (depending on the extent of your exam). You will need
These are procedures ordered for diagnostic purposes. Using CT for image guidance, biopsy and/or aspiration needles are directed towards a lesion and a tissue sample obtained for pathologic evaluation. Indications.

From January 1999 through November 2011, 305 CT-guided lung biopsies were performed of pulmonary nodules smaller than 1 cm in 290 patients. Of these 305 procedures, 108 aspirations, 164 core biopsies, and 33 combination uses of aspiration and core biopsy were performed. For 37 of the 305 procedures, a final

Biopsies were done of the liver in 88 patients, the pancreas in 28, the kidney in 20, and the retroperitoneum in 32; 30 underwent an aspiration procedure for characterization of an intraabdominal fluid collection. Accuracy of diagnosis was very high for hepatic. (99%).
The study group consisted of patients suspected on clinical grounds of having spontaneous disk space infections in whom CT-guided percutaneous needle aspiration procedures of the intervertebral disk space were performed by radiologists. The criteria used by clinicians for referral of patients for this procedure were not
