A 65-year-old woman was addressed to the Department of Radiology for assessment of dementia. Mnesic tests found moderate memory problems with mini-mental state (MMS) measured at 23/30. Symptoms were essentially marked by behavioral disorders of gradual onset for 2 years (decline in activity and empathy for her family). She was addressed for assessment of Alzheimer’s type dementia. MRI examinati...

Methods 373 women with symptomatic uterine fibroids were screened with MRI exams with and without contrast utilizing T2 coronal and axial, T2 fat suppressed sagittal, T1 axial precontrast images, and post contrast fat saturated images in 3 planes. Uterine masses were classified by their intensity on T2 weighted images relative to normal myometrium (hypointense, isointense, or hyperintense as we...

Figure 1. Magnetic resonance imaging of the brain demonstrating peripheral enhancement of the scalp abscess alongside noticeable enhancement of the adjacent soft tissues, pathological bone, and underlying pachymeningeal layer enhanced on a coronal T1W slice (left) with a clear intra-osseous edematous edema in keeping with osteomyelitic changes isolating a central bone sequestrum, communicating ...

prior to therapy in a patient with history of right nephrectomy for RCC and local recurrence in the nephrectomy bed (box). ASL MRI shows high levels of perfusion within the mass, similar to those of the renal cortex in the left kidney (arrow). Coronal T2-weighted (C) and perfusion (D) images of the same patient obtained 1 week after initiation of antiangiogenic therapy with sorafenib and bevaci...

An elderly patient with asymptomatic bilateral Bochdalek hernias is reported. The chest roentogenogram showed dome-shaped supradiaphragmatic masses about 6 cm in diameter in the posteromedial regions of both sides of the lungs. Computed tomography showed a discontinuity of the lines of diaphragmatic musculature in the left thorax, and a mass with a homogenous low density area indicative of fatt...

introduction: fearless removal of tooth structure during canal preparation and shaping has negative effects on the prognosis of treatment. on the other hand, sufficient pre-enlargement facilitates exact measurement of the apical size. the present in vitro study aimed to compare the efficacy of gates-glidden drills, k3, protaper, flexmaster and race instruments in dentin removal during coronal f...

introdouction: it is important for the clinician to be aware regarding the necessary thickness of materials used as intra-orifice coronal barriers to prevent microleakage. the purpose of this in vitro study was to compare coronal microleakage of three different thicknesses of white and gray angelus mineral trioxide aggregate (wamta, gamta). materials and methods: a total of 66 canals of extract...

BACKGROUND AND PURPOSE During surgical removal of a vestibular schwannoma, correct identification of the facial nerve is necessary for its preservation and continuing function. We prospectively analyzed the spatial relationship between vestibular schwannomas and the facial nerve using 3D T2-weighted and postcontrast T1-weighted spin-echo (SE) MR imaging. METHODS Twenty-two patients with a uni...

PURPOSE To investigate the clinical utility of the reverse gradient algorithm in correcting distortions in diffusion-weighted images of the cervix and for increasing diagnostic performance. MATERIALS AND METHODS Forty-one patients ages 25-72 years (mean 40 ± 11 years) with suspected or early stage cervical cancer were imaged at 3T using an endovaginal coil. T2 -weighted (W) and diffusion-weig...

BACKGROUND AND PURPOSE The reported MR imaging characteristics of cavernous sinus cavernous hemangiomas (CSCHs) in the literature are nonspecific. The purpose of our study was to explore dynamic enhancement features of CSCHs on conventional contrast-enhanced MR imaging and to correlate these features with histopathologic subtypes. MATERIALS AND METHODS Twenty-one patients (8 male and 13 femal...
