Objective: This study aimed to evaluate the sensitivity and specificity of the vessel signs, including the Vessel Flow Void Sign (VFVS) and the Hyperintense Vessel Sign (HVS) in Fluid Attenuated Inversion Recovery (FLAIR) images during the differentiation of Mitochondrial Encephalopathy, Lactic Acidosis, and Stroke-like Episodes (MELAS) in Acute Ischemic Stroke (AIS).
Methods: Magnetic Resonance Imaging (MRI) scans of 13 MELAS and 20 AIS patients were obtained during the acute stage of the diseases (median time to scan <1 day from symptom onset). To evaluate VFVS and HVS on the FLAIR images, Logistic Regression was used to analyze their correlation with MELAS.
Purpose: This study aimed to evaluate the amide proton transfer (APT) values in neonates with mild hypoxic-ischemic encephalopathy (HIE) using APT imaging.
Method: A total of 30 full-term neonates with mild HIE (16 males and 14 females; mean postnatal age 4.2 days, age range 2-7 days) and 12 normal neonates (six males and six females; mean postnatal age 3.
Background: The major factor for the appropriate treatment strategies for ischemia patients is its onset timing.
Purpose/hypothesis: To study to evaluate the diagnostic accuracy of T relaxation time in a rotating frame (T ρ) and apparent diffusion coefficient (ADC) from MRI to estimate ischemia stages.
Study Type: Prospective.
Objective: To analyse anatomical characteristics of the pelvic floor in young nulliparous volunteers based on three-dimensional MRI.
Methods: Thin-slice MRI was performed in 25 young nulliparous volunteers in Southern Medical University, MRI were imported into Mimics 10.01 for 3D reconstruction.
