Whole body soft tissue MRI

MRI examination of the whole body soft tissue is to perform MRI examination on the whole body to observe whether the soft tissue is different or not, and further diagnose the disease. Select different body coils or surface coils according to the part to be inspected to improve the signal-noise ratio and make the image clearer. Spin echo is the most basic scan sequence. Basic Information Specialist classification: growth and development check classification: nuclear magnetic resonance Applicable gender: whether men and women apply fasting: fasting Analysis results: Below normal: Normal value: no Above normal: negative: Check for abnormal lumps and areas. Positive: It is mainly used for diagnosing tumors, hematoma, abscesses, synovial cysts, etc. It can accurately determine its location, size, extent and neighboring structure involvement, but it is not possible to determine the nature of the lesion. In general, benign tumor MRI signal intensity is uniform, the boundary is clear, there is no peripheral edema, and the malignant tumor signal is uneven, the boundary is not clear, and there are often adjacent blood vessels and nerve invasion. Tips: Install artificial heart pacemakers and nerve stimulators, those with silver clips and metallic foreign bodies in the skull. Those who have had arterial surgery and cardiac surgery with artificial heart valves have metal objects in the examination site. (If the inside fixes the steel nails, etc.) This inspection is prohibited. Fasting water for 4 hours before imaging examination and training breath holding. Normal value Subcutaneous fat and bone marrow showed high signals on T1WI, T2WI and proton density images; cortical bone, air, ligament, tendon and fibrocartilage showed low signal; muscle and joint hyaline cartilage showed moderately low signal. Fluids, such as intra-articular fluid, inflammation or edema and tumor tissue, are low on T1WI and high on T2WI. The hematoma shows different signs of intensity depending on the length of the bleeding. Check for abnormal lumps and areas. Clinical significance Abnormal result It is mainly used for diagnosing tumors, hematoma, abscesses, synovial cysts, etc. It can accurately determine its location, size, extent and neighboring structure involvement, but it is not possible to determine the nature of the lesion. In general, benign tumor MRI signal intensity is uniform, the boundary is clear, there is no peripheral edema, and the malignant tumor signal is uneven, the boundary is not clear, and there are often adjacent blood vessels and nerve invasion. The population in need of examination has identified a patient with cancer. Precautions Forbidden before examination: fasting and water-free 4 hours before imaging examination, training patients to hold their breath. Requirements for inspection: Check the relaxed mood, follow the doctor's instructions to check, please bring the medical records, X-ray film, CT film, and previous MRI films along with the MRI room for reference. Inspection process Select different body coils or surface coils according to the part to be inspected to improve the signal-noise ratio and make the image clearer. Spin echo is the most basic scan sequence. T1WI displays a detailed anatomical structure for observing lesions in bone marrow and subcutaneous fat. T2WI is used to show the extent of lesion involvement in soft tissue. Coronal, sagittal, and cross-sectional scans were used depending on the joint and disease. Not suitable for the crowd Inappropriate crowd: 1. Those who install artificial heart pacemakers and nerve stimulators are forbidden to check. 2. It is forbidden to check if there is a silver clip in the skull and a metal foreign object in the eyeball. 3. The ECG monitor cannot enter the MRI examination room. Those who have undergone arterial surgery, have had heart surgery and have an artificial heart valve are forbidden to check. 4, a variety of critically ill patients: such as coma after trauma or accident, irritability, arrhythmia, respiratory insufficiency, constant blood loss and incontinence and so on. 5. Metal objects (such as internal fixed steel nails) cannot be inspected at the inspection site. 6. Pregnant women should be examined carefully. If they are pregnant, please inform the doctor. Adverse reactions and risks Nothing.
