BACKGROUND: Evaluation of impaired left ventricular (LV) filling has focused on intrinsic causes of LV dysfunction; however, pulmonary vascular changes may contribute to reduced LV filling and dyspnea. We hypothesized that lower total pulmonary vascular volume (TPVV) on computed tomography (CT) would be associated with dyspnea and decrements in LV end-diastolic volume, particularly among ever-smokers. METHODS: The Multi-Ethnic Study of Atherosclerosis recruited adults without clinical cardiovascular disease in 2000-02...

BACKGROUND HIV infections with concomitant immunologically-mediated disorders have been frequently described but there has been little research on the association between HIV and myasthenia gravis. MuSK myasthenia gravis coexisting with HIV is an even a rarer entity and can occur as a part of immune restoration disease. We report the case of a patient with asymptomatic HIV infection who presented with new-onset MuSK myasthenia gravis. CASE REPORT A 44-year-old African-American woman with HIV since 2004 and on highly active antiretroviral therapy (HAART) presented to the ED with complains of double vision and difficulty swallowing for 2 weeks...

BACKGROUND: The right-sided aortic arch (RAA) is a rare congenital defect of the aorta. The aim of the study was to assess the occurrence of RAA in diagnoses performed by the University Radiology Department and analyze the frequency of concomitant vascular abnormalities. METHODS: The database of the Radiology Department was retrospectively analyzed between January 2008 and May 2016 with the keyword "right aortic arch". Twenty patients with this diagnosis were identified from a total of 11,690 CT examinations of the chest area, 19,623 CT examinations of brain-supplying vessels, and 1863 MRI examinations of the heart and aortic arch or brain-supplying arteries...

Clinical case report and review of the literature. This is the first case of primary leiomyoma in an immunocompetent woman without previous history of uterine leiomyoma being reported in the literature to the best of our knowledge. Leiomyoma, a type of smooth muscle cell tumor, involving the vertebra is extremely rare. There were very few primary leiomyoma in patients with AIDS or in the immune-suppressed patients. This 48-year-old female came with H/o neck pain, weakness and bladder retention. On examination, tone increased in all four limbs, power on the right side of the limbs 4/5, power on the left upper limb 0/5, lower limb 3/5, left plantar was up going, decreased sensation over the left second cervical vertebra (C2) dermatome and all modalities decreased below C2...

BACKGROUND: Primary ciliary dyskinesia (PCD) and cystic fibrosis (CF) are increasingly compared. There are no chest magnetic resonance imaging (MRI) comparative studies of PCD and CF. We assessed clinical, functional, microbiological and MRI findings in PCD and mild CF patients in order to evaluate different expression of lung disease. METHODS: Twenty PCD (15.1 years) and 20 CF subjects with mild respiratory impairment (16 years, 70% with pancreatic insufficiency) underwent MRI, spirometry, and sputum cultures when clinically stable...

We describe a case of a 41-year old male patient with no significant prior medical history who presents with symptoms of Transient Ischemic Attack and stroke. Magnetic Resonance Imaging (MRI) of the brain identified areas of ischemia in the left side, and angiography showed occlusion of the left Medial Cerebral Artery (MCA). Cardiac Transthoracic Echocardiogram (TTE) for stroke evaluation incidentally noted a mediastinal abnormality leading to cancer work-up. Computer Tomography (CT) and (18) F-fluorodeoxyglucose (FDG) PET-CT scan of the chest incidentally revealed an avid 6 cm paraesophagial/subcarinal mass...

AIM: Accurate evaluation of distribution of disease and response to systemic anti-cancer therapy (SACT) is important in the optimal management of metastatic breast cancer. Whole-body magnetic resonance imaging (WB-MRI) has increased accuracy over computerised tomography of the chest, abdomen and pelvis (CT-CAP) for detecting liver and bone disease, but its effect on patient management is largely unexplored. This study investigates the effects of using WB-MRI alongside CT-CAP on SACT decisions in standard clinical practice for patients with metastatic breast cancer...

Azygous Vein Aneurysm (AVAs) is an uncommon cause of mediastinal mass. They are typically asymptomatic and do not commonly require treatment. They may mimic mediastinal adenopathy on chest radiographs. We present a case of AVAs found during evaluation of chest pain in a patient who was also found to have pulmonary thromboembolism. The mass was worked up with cross-sectional imaging techniques using both Computerized Tomography (CT) and Magnetic Resonance Imaging (MRI) and ultimately Positron Emission Tomography (PET)...

PURPOSE: Amount of fibroglandular tissue (FGT) and level of background parenchymal enhancement (BPE) in breast dynamic contrast enhanced magnetic resonance images (DCE-MRI) are suggested as strong indices for assessing breast cancer risk. Whole breast segmentation is the first important task for quantitative analysis of FGT and BPE in three-dimensional (3-D) DCE-MRI. The purpose of this study is to develop and evaluate a fully automated technique for accurate segmentation of the whole breast in 3-D fat-suppressed DCE-MRI...

PURPOSE: Respiratory motion compensation in PET/CT and PET/MRI is essential as motion is a source of image degradation (motion blur, attenuation artifacts). In previous work, we developed a direct method for joint image reconstruction/motion estimation (JRM) for attenuation-corrected (AC) respiratory-gated PET, which uses a single attenuation-map (μ-map). This approach was successfully implemented for respiratory-gated PET/CT, but since it relied on an accurate μ-map for motion estimation, the question of its applicability in PET/MRI is open...

Secondary or metastatic cardiac tumors are about 20-40 times more common than primary benign or malignant cardiac tumors. Cardiac metastases are more frequent in carcinomas, they usually appear in patients over 50 years and the involvement by gender is similar. Any tumor can cause cardiac or pericardial metastasis, although isolated or combined tumor invasion of the pericardium is more common. Transthoracic echocardiography (TTE) is the primary diagnostic procedure, followed by computed tomography (CT) and cardiac magnetic resonance imaging (MRI) to verify positive findings and to analyze other structures of the mediastinum and chest...

BACKGROUND: Cardioprotective value of ischemic post- (IPostC), remote (RIC) conditioning in acute myocardial infarction (AMI) is unclear in clinical trials. To evaluate cardioprotection, most translational animal studies and clinical trials utilize necrotic tissue referred to the area at risk (AAR) by magnetic resonance imaging (MRI). However, determination of AAR by MRI' may not be accurate, since MRI-indices of microvascular damage, i.e., myocardial edema and microvascular obstruction (MVO), may be affected by cardioprotection independently from myocardial necrosis...

Talaromyces marneffei (also called Penicilliosis Marneffei or T. marneffei) is a rare fungal disease that is prevalent mainly in Southeast Asia and commonly seen in immunocompromised hosts. It was rarely observed in immunocompetent hosts. We report a case of acute disseminated T. marneffei in an immunocompetent patient in the non-prevalent region. This patient had never visited the endemic area. The patient experienced a persistent fever. Brain CT and magnetic resonance imaging (MRI) showed a mass in the right frontal with osteolytic damage...
