MRI Head With IV Contrast There is no relevant literature to support the use of MRI head performed only with IV contrast in this clinical scenario. MRI Head Without and With IV Contrast MRI is the imaging test of choice in the evaluation of suspected progressive inflammatory conditions, such as multiple sclerosis or neuropsychiatric systemic lupus erythematosus. In the assessment of known ICH, MRI is usually not required unless there is suspicion for an underlying mass or lesion or if axonal shear injury is suspected. MRI without and with IV contrast may be performed if intracranial infection, tumor, inflammatory lesions, or vascular pathologies are suspected. MRI Head Without IV Contrast MRI is complementary to CT in the evaluation of suspected progression of intracranial mass lesions, infection, and ischemia and may be performed as a first-line test instead of CT. However, the literature search did not identify any studies regarding the use of MRI in the evaluation of acute or worsening mental status changes in a patient with known intracranial pathology. Advantages of MRI include higher sensitivity for the detection of ischemia, encephalitis, subtle cases of SAH, and enhancement of pathology compared with CT and the potential to use advanced imaging applications that may provide critical information, such as diffusion-weighted imaging, MR perfusion, susceptibility-weighted sequences, and MR spectroscopy. Disadvantages of MRI include longer examination time, susceptibility to motion artifacts, and implanted devices that are not MRI safe [2]. Variant 3: Adult. Altered mental status. Suspected medical illness or toxic-metabolic cause. Initial imaging. Acute mental status changes may be triggered by a wide range of medical conditions, including drugs and intoxication, system or organ dysfunction, and metabolic or endocrine factors.
