“…There is a broad range of methods available to improve liver biopsies, i.e., guidance with ultrasound/computed tomography/MRI, cutting needles, automatic devices [ 18 – 20 ]. In the present study, DE CT linearly blended images alone were not superior in reducing metal artifacts sufficiently nor in improving image quality in comparison to SE CT.…”

Purpose To evaluate dual-energy CT (DE) and dedicated metal artifact reduction algorithms (iMAR) during CT-guided biopsy in comparison to single-energy CT (SE). Methods A trocar was placed in the liver of six pigs. CT acquisitions were performed with SE and dose equivalent DE at four dose levels(1.7–13.5mGy). Iterative reconstructions were performed with and without iMAR. ROIs were placed in four positions e.g. at the trocar tip(TROCAR) and liver parenchyma adjacent to the trocar tip(LIVER-1) by two independent observers for quantitative analysis using CT numbers, noise, SNR and CNR. Qualitative image analysis was performed regarding overall image quality and artifacts generated by iMAR. Results There were no significant differences in CT numbers between DE and SE at TROCAR and LIVER-1 irrespective of iMAR. iMAR significantly reduced metal artifacts at LIVER-1 for all exposure settings for DE and SE(p = 0.02-0.04), but not at TROCAR. SNR, CNR and noise were comparable for DE and SE. SNR was best for high dose levels of 6.7/13.5mGy. Mean difference in the Blant-Altman analysis was -8.43 to 0.36. Cohen’s kappa for qualitative interreader-agreement was 0.901. Conclusions iMAR independently reduced metal artifacts more effectively and efficiently than CT acquisition in DE at any dose setting and its application is feasible during CT-guided liver biopsy.

“…CT-guided procedures emerged and developed in parallel with CT technology, the first CT-guided biopsy being performed in 1975 on a retroperitoneal tumor, just four years after CT was introduced in the clinical practice [2]. Shortly thereafter, these procedures had become widespread, their usage gaining momentum in the 90’s after the introduction of multi-slice spiral CT technology[3].…”

Background and aimsDespite their usefulness, CT-guided procedures have a low profile in Romania. The current study has the purpose of describing a first experience in performing these procedures.MethodsTumors and fluid collections that were inaccessible for biopsy or drainage by ultrasound or endoscopic guidance were included. The procedures were performed using a 64-slice GE Optima CT660 CT scanner. The biopsies were carried out using the coaxial technique with an 18 G semiautomatic needle. The drainages were performed using 10 F pig-tail drains that were inserted using the Seldinger technique. Data regarding the size and location of the target lesion, puncture technique, success and complication rates were recorded.ResultsBetween May 2017 and April 2018, 30 procedures were performed, of which 26 biopsies and 4 drainage insertions. Of the biopsies 3 were mediastinal, 8 pulmonary, 6 retroperitoneal, 4 pelvic, and 5 of the bone. The drainages were performed for pelvic lymphoceles. The average lesion size was 3.2 cm (0.7–9 cm), with a depth from the skin of 9.1 cm (0.6–15.2 cm). The average procedure duration was 58 minutes (31–93 minutes). A conclusive histopathological diagnosis was set after 92.3% of biopsies. Three procedures resulted in complications, two being minor (hemothorax, soft tissue hematoma) and one severe (tension pneumothorax requiring drainage).ConclusionsCT guidance offers safe access to lesions that cannot be biopsied or drained under ultrasound or endoscopic guidance.

“…Core needle biopsy of tumors is a pivotal tool for cancer diagnosis and its accuracy is dependent on the correct placement of the biopsy needle in the tumor. The use of PET/CT guidance is of growing importance for interventional procedures and several studies report that it has potential for improving targeting and diagnostic efficiency. It has also been shown that injecting the patient with 2‐deoxy‐2‐( 18 18F)fluoro‐D‐glucose ( 18 F‐FDG) prior to a core biopsy procedure (i.e., harvesting of small cylinders of tissue) and then measuring the activity distribution along the specimen using autoradiography (ARG) can provide information about the metabolic activity within the specimen with a spatial resolution much higher than that of PET .…”
