Regional cerebral blood flow (CBF) and cerebrovascular reactivity (CVR) in young and elderly participants were assessed using pulsed arterial spin labeling (ASL) and blood oxygenation level-dependent (BOLD) magnetic resonance imaging (MRI) techniques in combination with inhalation of CO2. Pulsed ASL and ...

A 55-year-old male presented with fever, stupor, aphasia, and left hemiparesis. A history of head trauma 3 months before was also reported. Cranial magnetic resonance imaging revealed slight contrast enhancement of lesions under the right frontal skull plate and right frontal lobe. Because of deteriorati...

ABSTRACT Objective: To determine the specificity, sensitivity, accuracy, likelihood, and correlation of the findings of meniscal tests and magnetic resonance imaging (MRI) to knee video arthroscopy., Methods: A cross-sectional study, conducted between June and December 2015, which evaluated 84 patien...
ABSTRACT Most stress fractures occur in the lower limbs and are rarely observed in the , upper limbs. The second metacarpal is the longest of all the metacarpals and has the largest base, articulating with the trapezium, trapezoid, capitate, and third metacarpal. In athletes, stress fractures in non-weig...
Abstract Objective To determine the prevalence of femoroacetabular impingement morphology (FAIM), cam- or pincer-type, by magnetic resonance imaging (MRI) in asymptomatic adolescent soccer players, and to evaluate the possible correlation between alterations on MRI and clinical examination findings. Me...
Introducción: La miopatía y fibrosis auricular representan el sustrato protrombótico y proarrítmico en pacientes con fibrilación auricular (FA). Estudios recientes muestran relación entre el strain auricular izquierdo (SAI), eventos cardiovasculares y recurrencia en pacientes con FA. La asociación...

Background: To evaluate the imaging findings in patients with breast cancer diagnosed before age 40 and their
correlation with histological type and molecular subtype. Methods: A descriptive, retrospective, single-center study was conducted by reviewing imaging exams and medical records, after approval o...
El Síndrome Hemolítico Urémico asociado a diarrea (SHU+D) es un desorden multisistémico en el cual el compromiso neurológico se asocia a empeoramiento del pronóstico. Una causa importante de daño neurológico permanente es el compromiso cerebrovascular. OBJETIVO: Reportar dos casos pediátricos de...
Abstract Trigeminal trophic syndrome is an uncommon cause of facial ulcers, that affects the sensitive area of the trigeminal nerve. We present the case of an 84-year-old patient with ulcerated facial trigeminal trophic syndrome, and report the development of a clinico-dermoscopic approach for his clinic...
Abstract OBJECTIVE The aim of this study was to investigate the effect of radiology nursing intervention in abdominal examination at 3-T MRI. METHOD 60 patients with abdominal diseases were divided into two groups randomly: MR nursing intervention group and control group. All the patients underwent abd...
