BACKGROUND: Experimental data show that the right ventricle (RV) is more resistant to ischemia than the left ventricle. To date, limited data are available in humans because of the difficulty of discriminating reversible from irreversible ischemic damage. We sought to characterize RV ischemic injury in patients with reperfused myocardial infarction using cardiovascular magnetic resonance.

METHODS AND RESULTS: In 3 tertiary centers, 242 consecutive patients with reperfused acute ...

OBJECTIVE: The purpose of this study was to assess the value of dual-source dual-energy CT in the evaluation of complex cystic renal masses.

SUBJECTS AND METHODS: Seventy patients underwent contrast-enhanced dual-energy CT that included true unenhanced images acquired in single-energy mode, corticomedullary phase images acquired in dual-energy mode, and nephrographic phase images acquired in single-energy mode. Virtual unenhanced, blended weighted-average, and color-coded iodine overlay ...

RATIONAL AND OBJECTIVES: To investigate whether a nonlinear-blending algorithm improves tumor conspicuity and image quality in the evaluation of renal masses at dual-energy computed tomography (DECT) during nephrographic phase of enhancement.

MATERIALS AND METHODS: The Institutional Review Board approved this retrospective study from archival material from patients consenting to the use of medical records for research purposes. A retrospective review of contrast-enhanced abdominal DECT ...

Delayed-contrast-enhancement (DCE) magnetic resonance imaging (MRI) can identify areas of myocardial damage in patients with acute myocarditis (AM). The aim of this study was to assess the electrocardiographic findings in AM diagnosed by DCE-MRI. Eighty-one patients (72 men, 35 ± 13 years) with AM were prospectively enrolled. All of them underwent MRI and 12-lead-ECG recordings. In the admission electrocardiogram (ECG 1), as well as in that obtained 48 h later (ECG 2), the following ...

PurposeTo describe the magnetic resonance imaging (MRI) pattern of muscle involvement and disease progression in five patients with late-onset Charcot-Marie-Tooth (CMT) disease type 2 F, due to a previously unknown mutation.Materials and methodsFive patients (three males, two females) underwent MRI of the lower limbs to define the pattern of muscle involvement and evaluate the muscle fat fraction (MFF) of residual thigh muscle with gradient-echo (GRE) dual-echo dual-flip angle technique. ...

OBJECTIVE: Cardiac involvement is not rare in systemic amyloidosis and is associated with poor prognosis. Both (99m)Tc-diphosphonate imaging and cardiac MRI with late gadolinium enhancement are considered valuable tools in revealing amyloid deposition in the myocardium; however, to our knowledge, no comparative study between the two techniques exists. We compared findings of these two techniques in patients with transthyretin-familial amyloid polyneuropathy (FAP).

SUBJECTS AND METHODS: ...

OBJECTIVES: Acute type B aortic dissection can have a stable course or evolve into aneurysm and subsequent adverse events. The aim of this systematic review was to analyze the morphologic predictors of an adverse course to establish their validity based on consistency of results.

METHODS: Fifty-one studies were included in this review, reporting on aortic size, false lumen (FL) size, primary entry tear (ET) size and location, status of FL thrombosis, number of ETs, branch vessels ...

OBJECTIVES: Right ventricular (RV) myocarditis (MY) is unrecognized, and its prevalence is unknown. We evaluated the prevalence of RV involvement in acute MY and its association with cardiac events (cardiac death, cardiac arrest, ventricular assist device, transplantation, and appropriate ICD intervention).

METHODS: We enrolled 151 patients who underwent cardiac magnetic resonance for clinical suspicion of acute MY. The CMR protocol included T2-STIR images for edema detection, ...

AIMS: Left atrium can be involved by amyloid deposition in familial amyloid polyneuropathy (FAP). The aim of our study is to assess left atrium function in atrial amyloidosis.

METHODS: Twenty-eight FAP patients (53 ± 12 years) and a control group of 22 asymptomatic individuals (49 ± 11 years) underwent strain echocardiography and cardiac magnetic resonance (CMR). CMR by late gadolinium enhancement (LGE) was used to assess the left atrium amyloid deposition, whereas strain ...

Cardiac amyloidosis is a rare, infiltrative cardiomyopathy that presents with thickened ventricular walls and progressive heart failure. The morphological findings and clinical features are shared with many other diseases (i.e. hypertrophic cardiomyopathy, 'athlete's heart,' Fabry disease, and hypertensive cardiomyopathy), and misdiagnosis occurs frequently. Cardiologists have many instruments that can help reach a correct diagnosis in a relatively short time. As tiles of a mosaic are ...

Considering that multiple imaging examinations are often necessary for monitoring Crohn's disease (CD) activity and severity in order to guide and monitor appropriate treatment, the ideal imaging test would be reproducible, well tolerated by patients, and free of ionizing radiation. For these reasons recent studies have highlighted the role of a magnetic resonance imaging (MRI) technique optimized for small bowel imaging in the evaluation of small bowel disorders. In this regard there ...

OBJECTIVE: To evaluate the accuracy of a semiautomatic quantification of left ventricular (LV) volumes and ejection fraction (EF) using two-dimensional (2D) feature tracking imaging (FTI).

METHODS: Thirty-four consecutive subjects (11 patients with dilated cardiomyopathy, 13 with hypertrophic cardiomyopathy, and 10 subjects with no cardiac disease) underwent, on the same day, trans-thoracic echocardiography (TTE) examination, FTI, and cardiac magnetic resonance imaging (MRI), as gold ...

ObjectiveThe purpose of this study was to describe the MR imaging findings of Nuck canal endometriosis (NCE).Materials and methodsIn a 10-year period, 486 out of 612 patients, with laparoscopically and/or surgically proven diagnosis of pelvic endometriosis, underwent MR imaging examination. The examinations were reviewed by two urogenital experienced radiologists working in consensus. Data analysis included: lesions location, size, morphological and signal intensity pattern, involvement ...

BACKGROUND: We sought to assess left atrial (LA) morphology and function in patients with transthyretin cardiac amyloidosis (TTR-CA) and hypertrophic cardiomyopathy (HCM). Primarily, longitudinal deformation (reservoir) and pump function were the focus of vector-velocity strain echocardiography imaging.

METHODS AND RESULTS: The study group comprised 32 patients (mean age 57.7±15.4 years, 16 in each group), and 15 healthy controls. Diagnosis of TTR-CA was based on echocardiography and ...

OBJECTIVES: Forty sites were involved in this multicenter and multivendor registry, which sought to evaluate indications, spectrum of protocols, impact on clinical decision making and safety profile of cardiac magnetic resonance (CMR).

MATERIALS AND METHODS: Data were prospectively collected on a 6-month period and included 3376 patients (47.2 ± 19 years; range 1-92 years). Recruited centers were asked to complete a preliminary general report followed by a single form/patient. Referral ...
