Penile emergencies: a review of the main conditions
Abstract Acute penile conditions, which typically have a traumatic, vascular, or infectious etiology, are rather uncommon and often require prompt medical evaluation. Penile emergencies can be treated conservatively or surgically, and their management often relies on the results of imaging examinations. Because of its high spatial resolution and wide availability, as well as the fact that it does not involve the use of ionizing radiation, ultrasound is the imaging modality of choice in the initial evaluation of penile emergencies. Inconclusive cases can be further evaluated with magnetic resonance imaging. The main purpose...

Benign ovarian lesions with restricted diffusion
Abstract Developments in magnetic resonance imaging have expanded its role in the assessment of the female pelvis, including the diagnosis of ovarian lesions. In this setting, diffusion-weighted imaging has proven its diagnostic value, which is particularly important in differentiating between benign and malignant ovarian tumors. In general, the latter show restricted diffusion, whereas the former do not. Exceptions include teratomas, endometriomas, hemorrhagic cysts, ovarian abscesses, ovarian infarction, and some benign stromal tumors. The aim of this review is to draw attention to benign ovarian lesions with restricted ...

SPECT/CT with 99mTc-sestamibi for the evaluation of skeletal muscle perfusion after electrical muscle stimulation in athletes
Conclusion: 99mTc-sestamibi SPECT/CT is an objective means of evaluating blood flow in muscles submitted to EMS, which appears to promote significant increases in such blood flow.Resumo Objetivo: O objetivo deste estudo foi avaliar o efeito da estimula ção elétrica transcutânea na musculatura esquelética utilizando-se SPECT/CT com 99mTc- sestamibi. Materiais e Métodos: Foram prospectivamente avaliados 20 atletas masculinos de polo aquático (18-36 anos de idade; média de 25 anos). Todos os atletas foram submetidos a SPECT/CT com 99mTc- se stamibi das coxas antes e após estimulação elétrica transcutânea dos ...

Changes in temporomandibular joint anatomy, changes in condylar translation, and their relationship with disc displacement: magnetic resonance imaging study
Conclusion: Changes in the shape of the articular eminence seem to predispose to progression of internal derangement of the TMJ.Resumo Objetivo: Verificar a correla ção entre as alterações das superfícies articulares e da translação condilar com o deslocamento de disco da articulação temporomandibular. Materiais e Métodos: Foram analisados os exames de ressonância magnética de 2076 articulações temporomandibulares de pacientes sintomáticos de de sordens temporomandibulares. A deformidade do disco articular, as alterações nas superfícies articulares do côndilo, da fossa glenoide e da eminência articula...

Initial chest X-ray findings in pediatric patients diagnosed with H1N1 virus infection
Conclusion: In pediatric patients with H1N1 virus infection, the main alterations on the initial chest X-rays are peribronchovascular opacities, nonspecific alveolar opacities, and consolidations. Although the definitive diagnosis of H1N1 virus infection cannot be made on the basis of imaging characteristics alone, using a combination of clinical and radiographic findings can substantially improve the diagnostic accuracy.Resumo Objetivo: Avaliar os achados na radiografia de t órax de pacientes com diagnóstico de infecção pelo vírus influenza. Materiais e Métodos: Revisamos, retrospectivamente, os achados na radiogr...

Radiological aspects in computed tomography as determinants in the diagnosis of pulmonary tuberculosis in immunocompetent infants
Conclusion: The radiological presentation of pulmonary tuberculosis in young children differs from that described in older children and adults. CT is an effective method for the early diagnosis of pulmonary tuberculosis in immunocompetent infants, allowing the rapid institution of specific treatment, which is crucial for halting disease progression, as well as for preventing local and systemic complications.Resumo Objetivo: Descrever achados radiol ógicos na tomografia computadorizada (TC) de tórax de crianças imunocompetentes menores de 36 meses com tuberculose pulmonar.

Cerebral amyloid angiopathy-related inflammation: findings on magnetic resonance imaging
Abstract Hearing disorders are usually unilateral and are more common in women. They can be congenital or acquired, and hearing loss is categorized as sensorineural, conductive, or mixed. The onset of hearing loss can be progressive or sudden, and it is a common reason for seeking medical attention. In this context, computed tomography and magnetic resonance imaging have assumed critical roles in the search for an etiological diagnosis and in guiding the therapeutic approach. In this pictorial essay, we illustrate the common causes of hearing loss, discussing the possible differential diagnoses and highlighting the most re...
