BACKGROUND AND PURPOSE Increasing evidence suggests that carotid artery imaging can identify vulnerable plaque elements that increase stroke risk. We correlated recently proposed markers, soft and hard plaque thickness measurements on axial computed tomography angiography source images, with symptomatic disease status (ipsilateral stroke or transient ischemic attack) in high-grade carotid disea...

A 12-year-old-boy was admitted to our Medical Imaging Department for scrotal/perineal heamatoma and a painless partial erection after bicycle trauma. He had no other medical history. Doppler US and angiography of penile region were performed. A gray-scale US (axial view, Fig. A)) shows an irregular hypoechoic region within the echogenic cavernous tissue and cavernosal lacuna (arrows). The color...

OBJECTIVE To evaluate the accuracy of contrast enhanced electron beam computed tomography (EBCT) after acute myocardial infarction in determining patency of the infarct related artery and detecting high grade stenoses and occlusions in the coronary vessels. DESIGN Case study using blinded comparison with invasive coronary angiography. PATIENTS 36 patients (mean age 53 years) 4-70 days after...

OBJECTIVE It is widely recognized that hemodynamic and wall mechanical forces are involved in the initiation and development of atherosclerosis. In the coronary vasculature, these forces are likely mediated by arterial dynamics and geometry. This research examines the hypothesis that coronary artery motion and geometry affect the local predisposition to disease, presumably through their influen...

PURPOSE To determine whether a relationship exists between normal variations in anatomy of the circle of Willis and the size of the internal carotid arteries (ICA). METHODS MR angiograms and axial MR images of the brains of 104 patients were reviewed. Included were 10 patients with unilateral absence of the A1 segment of the anterior cerebral artery, 10 with hypoplasia of one A1 segment, 28 w...

Bifurcation of the carotid artery at a cephalic location greatly increases the risk associated with carotid endarterectomy (CEA). Mandibular subluxation (MS) can improve access to the cephalic location; however, the benefits of MS remain unclear. The present study objectively assessed the efficacy of MS. MS was performed with only wire fixation of healthy teeth in four patients (Group A), with ...

The postcranial system is composed of the axial and appendicular skeletons. The axial skeleton, which consists of serially repeating segments commonly known as vertebrae, protects and provides leverage for movement of the body. Across the vertebral column, much numerical and morphological diversity can be observed, which is associated with axial regionalization. The present article discusses th...

PURPOSE To compare the axial length (AL), anterior chamber depth (ACD) and intraocular lens power (IOLP) of IOLMaster and Ultrasound in normal, long and short eyes. METHODS Seventy-four normal eyes (≥ 22 mm and ≤ 25 mm), 74 long eyes (> 25 mm) and 78 short eyes (< 22 mm) underwent AL and ACD measurements with both devices in the order of IOLMaster followed by Ultrasound. The IOLP were calcula...

Title: With axial loading during MRI diurnal T2-value changes in lumbar discs are neglectable: a cross sectional study Authors: Leif Torén ([email protected]) Hanna Hebelka ([email protected]) Izabela Kasperska ([email protected]) Helena Brisby ([email protected]) Kerstin Lagerstrand ([email protected]) Version: 2 Date: 21 Dec 2017 Author’s respons...

PURPOSE To evaluate the association between the AL/CR ratio and refractive state and explore the effectiveness of this ratio in the assessment of myopia, especially when combined with uncorrected visual acuity in schoolchildren among whom myopia is common. METHODS Cross sectional study. 4686 children from 6 primary schools, aged from 6 to 12 years were selected using the clustered-stratified ...
