Abstract
OBJECTIVE To evaluate the success and complication rates of ultrasound-guided renal biopsy at a tertiary care hospital. MATERIALS AND METHODS This was a retrospective analysis of 97 ultrasound-guided renal biopsies, all performed by the same radiologist, between 1 March, 2017 and 31 October, 2019. RESULTS Of the 97 biopsies evaluated, 87 had a definitive pathological diagnosis. In five cases (5.4%), the biopsy results were inconclusive and a second procedure was required. In seven procedures (7.6%), there were complications, all of which were properly resolved. CONCLUSION Ultrasound-guided renal biopsy has proven to be a safe, effective method for the diagnosis of nephropathies, with high success rates.

Abstract
Objective To evaluate the accuracy of percutaneous transhepatic biliary biopsy (PTBB) in patients with suspected biliary obstruction. Materials and methods This was a retrospective analysis of 18 patients with obstructive jaundice who underwent PTBB. In each patient, three to ten fragments were collected from the lesion. The final diagnosis was confirmed in the pathology report. We also reviewed analyses of the results of laboratory tests performed before the procedure, as well as the Bismuth classification, clinical outcome, complications occurring during the procedure, access route, and materials used. Results Technical success was achieved in 100% of the PTBB procedures. Among the 18 patients clinically diagnosed with bile duct stenosis, the pathological analysis confirmed that diagnosis in 17. In one case, the pathological findings were considered false-negative. The predominant tumor was cholangiocarcinoma (seen in 50% of the cases). Sixteen of the procedures (88.9%) were performed without complications. Transient hemobilia occurred in one case, and cholangitis occurred in another. Conclusion PTBB is a safe, viable, simple technique with a high rate of true-positive results for the definitive diagnosis of obstructive jaundice.

Abstract
Objective To evaluate the imaging findings of 18F-fluorodeoxyglucose
positron emission tomography/computed tomography (18F-FDG PET/CT)
and computed tomography (CT) in patients with additional primary tumors,
correlating the results with those of the method used in order to elucidate
the diagnosis and of the pathology reports. Materials and Methods We retrospectively analyzed the medical records, pathology reports and images
of 11 patients who underwent CT, 18F-FDG PET/CT, or both. We
included patients with at least two tumors, with confirmed distinct
histopathological profiles, at different sites. Patients in whom there was
no diagnostic confirmation were excluded, as were those in whom the
additional lesion was suspected of being a metastasis of the first. Results New primary malignancies were identified in 11 patients, one new tumor being
found in 10 and two new tumors being found in 1. The confirmed sites of the
additional malignancies were the lung, kidney, prostate, jejunum, and
breast. Single or multiple percutaneous biopsies were performed in 10
patients, and 1 patient underwent a surgical procedure for diagnostic and
therapeutic purposes. The tumors were metachronous in 6 cases and
synchronous in 5. Conclusion CT and 18F-FDG PET-CT combined with multiple percutaneous biopsy
could facilitate the diagnosis of additional lesions, thus optimizing the
treatment and follow-up of the affected patients.

Abstract
Most tumors of the biliary tract are too small to have specific imaging
characteristics or for percutaneous puncture to provide sufficient material for
diagnosis. Percutaneous transhepatic biliary drainage, in addition to being a
well-established technique in the treatment of obstructive jaundice, provides
adequate access for sampling obstructive lesions. In cases of biliary lesions,
percutaneous transhepatic biopsy of the biliary tract has proven to be a useful
diagnostic technique, with a reported accuracy of over 90% at some referral
centers.

Abstract
The aim of this paper is to describe the use of a new ultrasound imaging
processing technique to guide biopsies of suspicious breast calcifications. We
used this technique in 13 patients with suspicious breast calcifications that
could not be submitted to stereotactic biopsy. Suspicious calcifications were
identified by ultrasound, and the biopsy was successfully performed in all
cases. Although mammography continues to be the method of choice for the
detection and characterization of microcalcifications, this new technique can be
an alternative means of guiding biopsy procedures in selected patients who are
not candidates for stereotactic biopsy.

Abstract
Objective To describe the technique of injecting hemostatic matrix, as well as the
experience of our interventional radiology department in its
application. Materials and Methods We conducted a single-center study with retrospective analysis of the
experience of our group in the use of hemostatic gelatin matrix in
percutaneous biopsies. Results In a total of 73 biopsies in different organs, such as the liver, kidney, and
spleen, hemostatic gelatin matrix was introduced into the coaxial needle.
The only complication observed was migration of the hemostatic matrix to the
left kidney collecting system, and that was resolved with clinical
treatment. There were no cases of bleeding after the injection of hemostatic
matrix. Conclusion The use of hemostatic matrices in the path of percutaneous biopsies is
another tool available for consideration in minimally invasive
procedures.
