Acute Headache

BACKGROUND: Headache is one of the most common complaint in medical practice and the most often neurological symptom. AIM: The aim of our study was to estimate the frequency of abnormal magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) findings in patients with non-acute headache without focal neurological abnormalities. MATERIAL AND METHODS: The results of the MRI and MRA were retrospectively analyzed. As major abnormalities, we took into account tumor, stroke, extraaxial collection, Chiari malformations, and vascular pathology (aneurysm and arterial-venous malformation). RESULTS: Two hundred twenty-five patients fulfilled the criteria. Out of 225 patients with median age of 37 (18–85) years, 78% of the patients were female and 22% were male. In total, we found 8.4% of major abnormalities. On MRI head scan without MRA analysis, we found 50.7% of normal finding, 47.1% of minor abnormalities and 2.2% of major abnormalities. On MRA scan, we found we found 52.9% of normal finding, 40.9% of minor abnormalities, and 6.2% of major abnormalities. CONCLUSION: Our study demonstrates a low but important diagnostic yield of MRI and MRA examination for patients with non-acute headache without focal neurological abnormalities.

Hypertrophic cardiomyopathy (HCM) is a global disease affecting people of various ethnic origins and both genders. HCM is a genetic disorder with a wide range of symptoms, including the catastrophic presentation of sudden cardiac death. Proper diagnosis and treatment of this disorder can relieve symptoms and prolong life. Non-invasive imaging is essential in diagnosing HCM. We present a review to deliberate the potential use of cardiac magnetic resonance (CMR) imaging in HCM assessment and also identify the risk factors entailed with risk stratification of HCM based on Magnetic Resonance Imaging (MRI).

Improving Patient Care

Magnetic resonance imaging (MRI) has become an indispensable tool in the assessment of malignant disease. With increasingly sophisticated systems and technical advancements, MRI has continued to expand its role in providing crucial information regarding cancer diagnosis and management. In gynecological malignancies, this modality has assumed greater responsibility, particularly in the evaluation of cervical and endometrial cancers. In addition to conventional imaging, innovative techniques such as dynamic contrast-enhanced MRI and diffusion-weighted MRI show promise in offering early assessment of tumor response. This paper reviews the current role of MRI in gynecological cancers and highlights the potential of novel techniques in improving patient care.

Magnetic Resonance Imaging Mri

Computed tomography (CT) and magnetic resonance imaging (MRI) are enabling more precise diagnosis and treatment planning in patients with diseases of the larynx. The aim of this article is to describe the role of these methods in assessment of the laringeal diseases and key local anatomic characteristics important for spread of the disease. CT and MRI have a valuable contribution to the staging of the tumors due to the possibility to show the relationship to the ventricular complex, involvement of the subumucosal spaces, defining craniocaudal and anterposterior extension, laringeal cartilage invasion, as well as regional lymph node metastases.

Objective We sought to assess the diagnostic yield of advanced noninvasive imaging in the evaluation of patients with pulsatile tinnitus. Background Pulsatile tinnitus can be caused by high-risk cerebrovascular pathologies such as arteriovenous fistulae. The role of advanced noninvasive imaging, including magnetic resonance angiography and magnetic resonance venography, in the diagnostic evaluation of pulsatile tinnitus is not well defined. Design and methods We performed a retrospective cohort study of patients presenting for outpatient diagnostic evaluation of pulsatile tinnitus from January 2018 to March 2020 at Weill Cornell Medicine. Patients with non-pulsatile tinnitus and established etiologic diagnoses were excluded. Systematic chart abstraction was summarized using standard descriptive statistics. Univariate logistic regression was used to identify factors associated with nondiagnostic noninvasive imaging. Results A total of 187 patients (139 (74.3%) women) took part in this study, with a mean age of 48.6 years (standard deviation ( SD) = 15.5 years) and a mean body mass index (BMI) of 26.9 kg/m2 ( SD = 6.1 kg/m2). Of the 187 patients, 121 (64.7%) underwent exclusively noninvasive imaging, and 66 (35.3%) patients also had digital subtraction angiography (DSA). In patients who had exclusively noninvasive imaging, 62 (51.2%) patients received a diagnosis. In patients who underwent noninvasive and DSA imaging, 14 (21.2%) patients received a diagnosis based on DSA. Patients who were older at symptom onset (odds ratio (OR) = 1.05; 95% confidence interval (CI) 1.01–1.09) and those with a lower BMI (OR = 0.88, 95% CI 0.77–0.98) were more likely to have nondiagnostic noninvasive imaging. Conclusion Noninvasive cerebrovascular imaging often uncovers the etiology of pulsatile tinnitus. DSA remains useful for additional evaluation for patients with specific associated features.
