BACKGROUND We tested the feasibility of a simple method for assessment of prostate cancer (PCa) aggressiveness using diffusion-weighted magnetic resonance imaging (MRI) to calculate apparent diffusion coefficient (ADC) ratios between prostate cancer and healthy prostatic tissue. METHODS The requirement for institutional review board approval was waived. A(More)
AIMS To establish the correlations between the ultrasound (US) BI-RADS classification and Tsukuba elastography score when assessing breast lesions. To determine which type of breast lesion (BI-RADS category) would benefit most from an elastographic assessment. PATIENTS AND METHODS The investigated sample of imaging comprised a number of 129 images(More)
We present the case of a 91-year old female, with no family history of malignancy, diagnosed with primary superficial leiomyosarcoma G1 of the scalp with frontal bone lysis and intracranial extension. The particularity of this case is the rarity of this tumor and the uncommon location. Also the bone involvement, present in our case, has been seen only in a(More)
We are reporting a case with decrease vision of the left eye, convergent strabismus of the left eye and diplopia. The neuro-ophthalmologic exam shows palsy of the left sixth cranial (abducens) nerve. The cerebral angiography exam reveals an aneurysm of the left communicating artery. After the neurosurgical approach and the clipping of the aneurysm, the(More)
Two quantitative ocular magnetic resonance imaging (MRI) methods for the clinical use in Ophthalmology and Radiology were developed. Ocular MRI images with spatio-temporal resoultions of 0.78/1.56/2/(5 to 84) mm/mm/mm/s were acquired from patients with diabetic retinopathy and normal subjects using a 1 T MRI system. T1 and T2 MRI relaxometry maps were(More)
AIMS The purpose of the study was to determine if the color quantitative analysis obtained on elastographic images of breast lesions could improve the benign-malignant differentiation, and also to identify some of the circumstances which would benefit most from such an analysis. PATIENTS AND METHODS The study design was a longitudinal prospective one, all(More)
PURPOSE To evaluate the potentials of T2 weighted (T2W)MRI and diffusion weighted (DW) MRI for prostate cancer(PCa) detection, local staging and treatment planning in high-risk group. MATERIAL AND METHODS Endorectal MRI was performed in 17 Romanian men (median age: 66 years; range: 58 75 years), prostate specific antigen (PSA) serum levels (median: 20 ng(More)
BACKGROUND AND PURPOSE The mastoid portion of the temporal bone has multiple functional roles in the organism, including regulation of pressure in the middle ear and protection of the inner ear. We investigated whether mastoid pneumatization plays a role in the protection of vital structures in the temporal bone during direct lateral trauma. MATERIAL AND(More)
We present the case of an adult patient with active post-primary pulmonary tuberculosis (TB) and discuss specific morphological and textural aspects found at high-field magnetic resonance imaging (MRI) of the lung. The 42-year-old man, heavy smoker, undertook a routine employment medical examination and was admitted to a referral pulmonology and TB center(More)
