Quantification of hepatic fat: evaluation of different magnetic resonance imaging measurement strategies in cases of homogeneous and heterogeneous distribution.

Objective: To evaluate three different measurements strategies to quantify hepatic steatosis and to investigate the differences between homogeneous and heterogeneous forms of hepatic steatosis.

Materials And Methods: Retrospective study conducted by magnetic resonance imaging review. We evaluated three different strategies measures for quantification of hepatic steatosis in two matched groups: homogeneous and heterogeneous steatosis.

Endometrioid adenocarcinoma with sacral metastasis.

Most bone tumors are metastatic. Breasts, lungs, kidneys, and thyroid are the primary sites most commonly involved in bone metastasis-type outcomes. This case study describes the involvement of a patient with a bone tumor located in the axial skeleton, initially in the sacral region.

Intramuscular adipose tissue, muscle area, and power as predictors of performance in breast cancer survivors.

Purpose: The decline in physical performance, assessed by physical tests such as the timed up and go (TUG) test, is a consequence of reduced physiological reserves at higher levels of a hierarchical process. This occurs due to changes in muscle architecture, including atrophy and fat infiltration into the muscles, which in turn lead to changes in muscle function, resulting in reduced muscle strength and power and, consequently, affecting physical performance. This study investigated predictive factors for physical performance in breast cancer survivor (BCS), focusing on intramuscular adipose tissue (IMAT), quadríceps muscle area (QMA), and muscular power.

Ultrasound measurement of thyroid volume in euthyroid children under 3 years of age.

Objective: To establish ultrasound reference values for thyroid volumes in children up to 3 years of age, given that ultrasound of the thyroid is an essential examination in the diagnosis of childhood thyroid disease.

Materials And Methods: This was a prospective study conducted in an iodine-sufficient city in southeastern Brazil. A total of 100 healthy children underwent clinical evaluation, anthropometric examination, and cervical ultrasound in accordance with conventional protocols.

Radiology report: what is the opinion of the referring physician?

Objective: To evaluate the opinion and perception of referring physicians regarding the radiology report, in order to develop tools that promote an improvement in its quality.

Materials And Methods: We prepared a questionnaire containing ten multiple choice questions about the radiology report, administering it to 70 physicians (35 specialists and 35 residents working in specialties other than radiology).

Results: Referring physicians (specialists and residents) showed a preference for structured reports, with a description explained in universal medical language and a complete conclusion listing the diagnostic possibilities with the degree of certainty.

Ultrasound evaluation of the penis.

Ultrasound is an excellent method for the study of penis. In this article, using a critical review of the literature and teaching files, we present examples of the major findings in the ultrasound routine, focusing on trauma, priapism, Peyronie's disease, and erectile dysfunction.

Excess Radiation to Newborns Hospitalized in the Intensive Care Unit.

Newborns in intensive care units are generally subjected to a great number of X-rays procedures and to the risk of radiation-induced damage. This study evaluated a possible excess radiation by excess of radiographs, excess of dose per radiograph or under-collimation of the X-ray beam. The mean of X-rays per newborn was 12 (1-65) during a mean hospitalization of 29 d (1-226 d).

Timing of thyroid ultrasonography in the etiological investigation of congenital hypothyroidism.

Objectives: To describe the findings of thyroid ultrasonography (T-US), its contribution to diagnose congenital hypothyroidism (CH) and the best time to perform it.

Subjects And Methods: Forty-four patients with CH were invited to undergo T-US and 41 accepted. Age ranged from 2 months to 45 years; 23 patients were females.

Sonographic evaluation of children with congenital hypothyroidism.

Objective: To establish benchmarks and study some sonographic characteristics of the thyroid gland in a group of euthyroid children aged up to 5 years as compared with age-matched children with congenital hypothyroidism.

Materials And Methods: Thirty-six children (17 female and 19 male) aged between 2 months and 5 years were divided into two groups - 23 euthyroid children and 13 children with congenital hypothyroidism - and were called to undergo ultrasonography.

Results: In the group of euthyroid children (n = 23), mean total volume of the thyroid gland was 1.

Laryngeal schwannoma: a case report with emphasis on sonographic findings.

Schwannomas are benign nerve sheath tumors composed of Schwann cells, which normally produce the insulating myelin sheath covering peripheral, cranial and autonomic nerves. Twenty-five to forty-five percent of all schwannomas occur in the head and neck region, but location of such tumors in the larynx is rarely observed. The present report is aimed at describing a clinical case of laryngeal schwannoma, with emphasis on sonographic findings.

Low-load resistance training promotes muscular adaptation regardless of vascular occlusion, load, or volume.

Purpose: This study investigates the impact of two different intensities and different volumes of low-load resistance training (LLRT) with and without blood flow restriction on the adaptation of muscle strength and size.

Methods: The sample was divided into five groups: one set of 20 % of one repetition maximum (1RM), three sets of 20 % of 1RM, one set of 50 % of 1RM, three sets of 50 % of 1RM, or control. LLRT was performed with (OC) or without (NOC) vascular occlusion, which was selected randomly for each subject.

Comparison between ultrasound and noncontrast helical computed tomography for identification of acute ureterolithiasis in a teaching hospital setting.

Context And Objective: Recent studies have shown noncontrast computed tomography (NCT) to be more effective than ultrasound (US) for imaging acute ureterolithiasis. However, to our knowledge, there are few studies directly comparing these techniques in an emergency teaching hospital setting. The objectives of this study were to compare the diagnostic accuracy of US and NCT performed by senior radiology residents for diagnosing acute ureterolithiasis; and to assess interobserver agreement on tomography interpretations by residents and experienced abdominal radiologists.
