1. The added value of non-contrast 3-Tesla MRI for the pre-operative localization of hyperparathyroidism
Abstract Objective: We investigated the efficacy of non-contrast 3-Tesla MR imaging added to the combination of sestamibi with99mTc (MIBI) scintigraphy and Ultrasonography (US) for the pre-operative localization of Primary Hyperparathyroidism (PHPT) lesions. Methods: A total of 34 parathyroid glands, including nine normal glands, were examined with MIBI, U

2. Enhancement patterns of adrenal nodules on magnetic resonance imaging
ABSTRACT Objective: To compare enhancement patterns of typical adrenal adenomas, lipid-poor adenomas, and non-adenomas on magnetic resonance imaging (MRI). Materials and Methods: Evaluation of adrenal nodules larger than 1.0 cm, with at least 2-year follow-up, evaluated on MRI in January 2007 and December 2016. Two different protocols were included - upper

3. Audio-vestibular and radiological analysis in Meniere’s disease
Abstract Objective: Intravenous gadolinium-enhanced inner ear magnetic resonance imaging (IV Gd-enhanced inner ear MRI) is a new technique for diagnosing Meniere’s disease (MD). Vestibular tests have also long been used forMD, but which tests should be included in the oto-neurological test battery remains controversial. The evaluation method to be used to

4. Adolescent depression and resting-state fMRI brain networks: a scoping review of longitudinal studies
The neurobiological factors associated with the emergence of major depressive disorder (MDD) in adolescence are still unclear. Previous cross-sectional studies have documented aberrant connectivity in resting-state functional magnetic resonance imaging (rs-fMRI) networks. However, whether these findings precede MDD onset has not been established. This scopin

5. The clinical features and image characteristics of Meniere’s disease patients with endolymphatic hydrops confirmed by enhanced magnetic resonance imaging
Abstract Objectives: To analyze and summarize the clinical features and image characteristics of Meniere’s Disease (MD) patients with Endolymphatic Hydrops (EH) confirmed by enhanced Magnetic Resonance Imaging (MRI). Methods: 252 MD patients with EH confirmed by MRI were enrolled. All patients met the diagnostic criteria forMD and underwent intravenous g

9. Extra-pituitary midline structural abnormalities associated with ectopic posterior pituitary detected on a new rapid MRI protocol (FAST1.2)
ABSTRACT Objective: Test if the MRI FAST1.2 protocol can detect extra-pituitary midline structural brain abnormalities in patients with ectopic posterior pituitary (EPP), and highlighting their radiological-laboratory correlations. Subjects and methods: Cross-sectional study of patients with EPP and control group. All individuals were submitted to FAST1.2,

10. VI-RADS score system - A primer for urologists
ABSTRACT Bladder cancer (BCa) is one of the most common cancers worldwide and is also considered to be one of the most relapsing and aggressive neoplasms. About 30% of patients will present with muscle invasive disease, which is associated with a higher risk for metastatic disease. The aim of this article is to review the state of art imaging in Radiology, w

11. Flow volume measurement of arterial venous and cerebrospinal fluid in patients with multiple sclerosis
Resumo Antecedentes A esclerose múltipla (EM) é comumente descrita como uma doença autoimune, embora seu mecanismo exato permaneça desconhecido. Há estudos que afirmam que anormalidades no fluxo venoso podem estar relacionadas à patogênese da EM ou a muitas das manifestações clínicas associadas. Objetivo O objetivo deste estudo é avaliar os volu

12. NMR Relaxometry Applied to Chemical Studies of Paramagnetic Metal Cation Complexes: Fundamentals and Applications
Low field time-domain nuclear magnetic resonance (TD-NMR) relaxometry of paramagnetic metal cations (PMC) has been widely used to study and improve contrast agents for magnetic resonance imaging (MRI). However, despite its remarkable potential, TD-NMR is rarely used to study PMC complexes, and coordination compounds in non-biomedical application. Therefore,
