Emergencies involving the inguinal region and scrotum are common and can be caused by a plethora of different causes. In most cases, such conditions have nonspecific symptoms and are quite painful. Some inguinoscrotal conditions have high complication rates. Early and accurate diagnosis is therefore imperative. Ultrasound is the method of choice for the initial evaluation of this vast range of conditions, because it is a rapid, ionizing radiation-free, low-cost method. Despite the practicality and accuracy of the method, which make it ideal for use in emergency care, the examiner should be experienced and should be familiarized with the ultrasound findings of the most common inguinoscrotal diseases...

Although ultrasound is still the gold standard for the assessment of fetal malformations, magnetic resonance imaging (MRI) has gained great prominence in recent years. In situations in which ultrasound has low sensitivity, such as maternal obesity, abdominal scarring, and oligohydramnios, MRI has proven to be a safe and accurate method. Regarding fetal abdominal wall defects, MRI appears to be widely used in the prognostic assessment of gastroschisis with intestinal atresia or of complications of omphalocele, allowing better perinatal management and parental counseling...

The accurate diagnosis of pulmonary thromboembolism is essential to reducing the morbidity and mortality associated with the disease. The diagnosis of pulmonary thromboembolism is challenging because of the nonspecific nature of the clinical profile and the risk factors. Imaging methods provide the definitive diagnosis. Currently, the imaging method most commonly used in the evaluation of pulmonary thromboembolism is computed tomography. The recent development of dual-energy computed tomography has provided a promising tool for the evaluation of pulmonary perfusion through iodine mapping...

Objective: To present a quantitative system for assessing the quality of ultrasound examinations-SQUALUS-and to determine its reproducibility, taking into consideration the images on file, as well as the consistency between the images obtained and the final report. Materials and Methods: The system includes questions related to the number of images; the appropriateness of images in relation to the protocol established; focus adjustment; depth; gain; and appropriateness of the measurements for B-mode examinations...

Objective: The aim of this study was to identify radiological and clinical risk factors for death in newborns with necrotizing enterocolitis. Materials and Methods: This was a retrospective cohort study, based on radiological examinations and medical charts of 66 infants with necrotizing enterocolitis, as confirmed by a finding of intestinal pneumatosis (stage IIA, according to modified Bell's staging criteria). Radiological and clinical variables were evaluated...

Objective: To analyze the perception of the relevance of introducing bilingual (Portuguese-English) musculoskeletal imaging education into radiology and diagnostic imaging residency programs, describing the method used. Materials and Methods: To evaluate the relevance of incorporating the bilingual study of musculoskeletal imaging into medical residency programs, we administered a questionnaire, consisting of several multiple-choice questions and one subjective question, to 21 radiology residents at a private tertiary hospital...

Objective: The purpose of this study was to determine whether chemical-shift magnetic resonance imaging (MRI) could be useful in the diagnosis of osteoid osteoma when clinical and radiological tumor features are inconclusive. Materials and Methods: This retrospective study included 17 patients who underwent chemical-shift MRI for the evaluation of osteoid osteoma. For all patients, two musculoskeletal radiologists independently recorded signal intensities on in-phase and out-of-phase images in the nidus of the tumor, in abnormal-intensity bone marrow surrounding the lesion, and in normal-appearing bone marrow...

Objective: To show the initial (first-year) experience with 68 Ga-PSMA PET/CT at a clinic in Brazil. Materials and Methods: Over a one-year period, 96 examinations with 68 Ga-PSMA PET/CT (85 related to prostate cancer and 11 related to kidney cancer) were performed in 90 patients. Results: In the prostate and kidney cancer patients alike, the main clinical indication for 68 Ga-PSMA PET/CT was suspicion of recurrence during follow-up (in 65...

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 gamma probe. Results: We report the cases of six patients submitted to radioguided surgery, including three patients with bone lesions suspicious for metastasis, two patients suspected of recurrent sarcoma, and one patient with no previous diagnosis who had a nodular lesion on the left leg...

Objective: To evaluate the performance of computed tomography (CT)-guided percutaneous biopsy of abdominal lesions. Materials and Methods: This retrospective, single-center study evaluated patients submitted to CT-guided percutaneous biopsy of abdominal lesions at a cancer center, between January 2014 and June 2015. The images and patient medical records were reviewed using a standardized data collection form. Results: We included 225 procedures performed in 212 patients, of whom 143 (63...
