Computed tomography-guided percutaneous drainage of tension pneumomediastinum

Computed tomography-guided percutaneous biopsy of head and neck masses: techniq...

Abstract Objective: To assess the technique, efficacy, and safety of computed tomography (CT)-guided percutaneous biopsies of head and neck masses. Materials and Methods: This was a retrospective, single-center study of CT-guided percutaneous core-needle biopsies of head and neck masses. For the analysis of diagnostic accuracy, biopsy results were compared with the final diagnosis, which was determined by histo...

Estimating the productivity of radiologists in Brazil: the search for a benchmark

Abstract Objective: To determine the average productivity of radiologists, as measured by number of reports issued per 6-h shift, evaluating variables that could affect the results. Materials and Methods: This was a study utilizing an online questionnaire sent to radiologists affiliated with the Brazilian College of Radiology and Diagnostic Imaging. The questions were related to the demographic profile and prof...

Chest CT accuracy in the diagnosis of SARS-CoV-2 infection: initial experience ...

Abstract Objective: To evaluate the accuracy of chest computed tomography (CT) in patients with suspected severe acute respiratory syndrome-related coronavirus-2 (SARS-CoV-2) infection at a cancer center. Materials and Methods: This retrospective single-center study selected 91 patients who had chest CT and real-time polymerase chain reaction (RT-PCR) test collected at the same day. CT results were classified i...

Retrospective analysis of computed tomography-guided percutaneous nephrostomies...

Abstract Objective: To establish an overview of computed tomography (CT)-guided percutaneous nephrostomy performed at a referral center for cancer, addressing the characteristics of patients submitted to this intervention, as well as the indications for it, the technical specificities of it, and its main complications. Materials and Methods: This was a retrospective study involving a review of the electronic me...

Pseudomyxoma peritonei in a pediatric patient: A case report and literature review

Summary Introduction: Pseudomyxoma peritonei (PMP) is a rare clinical condition, with an incidence of 1-2 cases per million, characterized by the dissemination of mucinous implants on the peritoneal surface and progressive gelatinous ascites. Although it usually presents an indolent behavior, its non-specific clinical presentation contributes to many cases remaining undiagnosed until a laparotomy is performed. ...

Locoregional recurrence of Frantz’ tumor: a case report and review of the liter...

SUMMARY Frantz' tumours or solid pseudopapillary tumours of the pancreas are rare neoplasms with low malignant potential. Young women in the second to third decades of life are more frequently affected. The treatment of choice is resection of the lesion, which is often curative. The recurrence is uncommon when radical surgical resection is used. Radiological characteristics are important for the correct diagnos...

Computed tomography with a stomach protocol and virtual gastroscopy in the stag...

Abstract Objective: To evaluate the accuracy of multidetector computed tomography with a stomach protocol in staging of gastric cancer. Materials and Methods: We evaluated 14 patients who underwent computed tomography in a 16-channel scanner for preoperative staging of gastric adenocarcinoma between September 2015 and December 2016. All images were analyzed by the same radiologist, who had extensive experience ...

Computed tomography-guided preoperative localization of musculoskeletal lesions...

Abstract Objective: To describe the preoperative localization of musculoskeletal lesions with the radioguided occult lesion localization (ROLL) technique. Materials and Methods: In all cases, computed tomography-guided injection of technetium-99m sulfur colloid was performed, directly into or near the suspicious lesion, up to 36 hours before the surgical procedure. Lesions were detected intraoperatively with a ...

Extravasation of iodinated contrast medium in cancer patients undergoing comput...

Abstract Objective: The aim of this study was to evaluate the incidence of extravasation of iodinated contrast medium (ICM) at the site of intravenous injection in oncology patients submitted to computed tomography (CT). Materials and Methods: This was a retrospective, descriptive, single-center study that evaluated all patients who underwent CT with ICM administration and presented ICM extravasation, at a canc...
