reason for this examination: ischemic/hemorrhagic injury final report indication: 59-year-old man with change in mental status. evaluate for ischemic or hemorrhagic injury. comparison: none. technique: contiguous axial images were obtained through the brain. no contrast was administered. findings: there is no evidence of hemorrhage, edema, large masses, mass effect, or large territorial infarction. the ventricles and sulci are normal in size and configuration. no acute fractures are identified. a small subcentimeter area of low-attenuation is noted within the left supracortical white matter (2, 15), which could represent a prominent perivascular space or lacunar ischemic event. conclusion: no evidence of hemorrhage, edema, large masses, mass effect or infarction. mri is more sensitive to detect ischemic changes with diffusion- weighted imaging sequences and is recommended if clinically indicated and if there is no contraindication to mri. the study and the report were reviewed by the staff radiologist. dr. dr. radiology report chest (portable ap) study date of 10:30 am medical condition: 59 year old man s/p avr reason for this examination: r/o ptx final report
