Journal of Dentistry Indonesia
Objective: To examine the morphological properties of temporomandibular joint structures by magnetic resonance imaging (MRI) on patients with and without disc displacement (DD). Methods: Thirty-eight patients with disc displacement and 13 patients without disc displacement were included. Age, gender, and clinical findings such as pain, joint sounds of patients were recorded. The patients were classified as anterior disc displacement with reduction (ADDWR) group, anterior disc displacement without reduction (ADDWoR) group, and control group on MRI. Disc morphology was categorized as biconcave, hemiconvex, biconvex, biplanar, or folded. Condyle morphology was characterized as convex, angled, flat, or rounded. Articular eminence …

Objectives The aim was to evaluate the different findings of magnetic resonance brain imaging in epilepsy. Background Epilepsy is a common brain disease that affects both pediatrics and adults. The main role of neuroimaging in epilepsy patients is to identify underlying structural abnormalities. MRI has a high spatial resolution, soft tissue contrast and multiplanar capabilities making it the modality of choice in investigating patients with epilepsy. Patients and methods This study was conducted at the MRI Unit, Radiodiagnosis Department at Menoufia University Hospital from October 2019 to September 2021 with the approval of the Menoufia Review Board and prospectively performed …

Optimal Infusion Rate Of Hypertonic Saline To Encephalic Vessel Vasodilatation Using Magnetic Resonance Imaging In Normovolemic Dogs, Yoshiki Murakami, Kenji Tsukano, Haruyuki Hirata, Hiroshi Koie, Kazuyuki Suzuki
The Thai Journal of Veterinary Medicine
This study aimed to investigate, using magnetic resonance imaging, whether continuous hypertonic saline (HSS) infusion induces a superior vasodilating effect on the encephalic vessels compared to bolus infusion in dogs. The relative cross-sectional area of superior sagittal sinus increased to 1.96±0.09 and 1.69±0.31 times of the pre-value in the continuous and bolus groups, respectively, at t=30 min (p<0.001). However, the relative cross-sectional area of superior sagittal sinus was larger in the continuous group than that in the bolus group (p<0.001). The results suggest that continuous infusion of HSS might be superior to bolus infusion in inducing vasodilatation of the encephalic circulation.

Menoufia Medical Journal
Background Coronavirus disease-2019 (COVID-19) disease was primarily described as a pandemic of respiratory illness, however, with the disease progression, variable cases with extrapulmonary manifestations have been reported all over the world. Severe acute respiratory-syndrome coronavirus- 2 infection can affect different body systems with the neurologic, abdominal, thromboembolic, cardiac, mediastinal, and hematological manifestations that had been reported in many literatures. The understanding of this multisystemic involvement is being better understood as the pandemic progresses. Objective The aim was to study the different neuroimaging findings in patients with severe acute respiratory- syndrome coronavirus-2 infection and their clinical and epidemiological characteristics. Patients and …

The similarity between benign and malignant pathologies on magnetic resonance imaging (MRI) and a wide-ranging variability of the lesions from benign proliferative changes to invasive breast carcinoma cause a lower and wide-ranging specificity of breast MRI relative to its surpass sensitivity. A wide range of tissue components such as the skin, the adipose tissue, vascular and neural tissues, connective tissues, glandular tissues, ducts, and muscle tissues are found here all together. This pictorial review was aimed at deliberating benign mimickers of breast carcinoma on MRI and trying to call attention to the overlapping and distinctive features.

Turkish Journal of Medical Sciences
Background/aim: Sacrococcygeal teratomas (SCT) are known as rare tumors, but they are the most common tumor in fetuses and newborns. This study aims to present fetal magnetic resonance imaging (MRI) findings of SCT diagnosed prenatally and compare them with that of the prenatal Ultrasound (US) findings. Materials and methods: Eleven patients diagnosed as SCT prenatally by US and further assessed by MRI are included. MRI was performed via a 1.5-T magnet with a body coil. The presence, size, content extension, and compressive effects of each mass were determined and correlated with US findings and with postnatal examinations, including surgery and …

Background/aim: The purpose of this study is to determine the accuracy of bilateral inferior petrosal sinus sampling (IPSS) in lateralization and to investigate variables associated with accurate IPSS lateralization prediction. Materials and methods: Initially, data from 55 patients who underwent IPSS in our institution were reviewed retrospectively. IPSS lateralization and pituitary magnetic resonance imaging (MRI) results of these patients were compared with postoperative follow-up and immunohistochemical data to calculate the positive predictive values (PPVs) for IPSS and MRI. Variables likely to be associated with the accurate prediction of IPSS lateralization were analyzed. Results: Twenty-seven patients (85.2% female, mean age of …

Background/aim: Dynamic contrast enhanced magnetic resonance imaging (DCE-MRI) can in vivo characterize tumor microvascular environment. The aim of the present study was to reveal the DCE-MRI findings and to determine the correlation between these findings and immunohistochemical data in head and neck squamous cell carcinoma (HNSCC). Materials and methods: Thirty-three patients diagnosed with primary HNSCC were evaluated retrospectively. DCE-MRI was conducted in all cases. CD34, CD105, and ki-67 expressions were analyzed with immunohistochemistry in tissue sections to determine micro-vessel density and proliferative activity. Results: The DCE-MRI is a successful technique in distinguishing tumor tissue from normal tissue. It was determined …
