pelvic MRI

The pelvic MRI is an MRI scan of the pelvis to check for prostate, bladder and ovarian lesions. Drinking water 500ml 2 hours before the routine pelvic MRI imaging, the bladder is filled, if the intestinal tract can be used in advance to suppress the peristaltic drugs. Check the relaxation 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. Basic Information Specialist classification: growth and development check classification: nuclear magnetic resonance Applicable gender: whether men and women apply fasting: fasting Tips: Those who install artificial heart pacemakers and nerve stimulators are forbidden to check. 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 Judgment and evaluation of bladder ureter, prostatic vesicle uterus and its attachment lesions can be used to accurately determine the extent of tumor invasion and its relationship with surrounding structures. To understand the morphological changes of primary tumors and their diffusion and infiltration, and to determine the stage of the tumor to provide a basis for the development of treatment plans. Follow-up observation of the dynamic changes in the disease and recurrence. The diagnosis of postoperative complications is better than other methods, such as the identification of fresh hemorrhage (hematoma) and old hematoma, and the display of abscess. People who need to be examined: women in their reproductive years. Precautions Contraindications before the examination: 500ml of water in the 2 hours before the routine pelvic MRI imaging, so that the bladder is filled, if the intestinal tract can be used in advance to suppress the peristaltic drugs. 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 1, coil and body position: A body phased array coil or a body wrapped flexible coil is used. The supine position is advanced or advanced, and the center line is aligned with the upper edge of the pubic symphysis. 2. Conventional imaging orientation and sequence: Pelvic imaging was performed with cross-sectional T1WI and T2WI imaging, with sagittal and coronal imaging. Increase fat suppression techniques or use proton imaging depending on the situation. The conventional layer has a thickness of 3 to 5 mm and a pitch of 30%. The phase encode direction: the LR direction is used for the cross section, the LR direction or the HF direction is used for the sagittal plane, and the LR direction is used for the coronal plane. 3. Contrast enhancer: Contrast agent: 0.5 mol/L (Gd-DTPA), 0.1 mmol/Kg, 0.5-1 ml/s intravenously. Scanning sequence: T1WI scan of the lesion with cross-section, coronal plane, and sagittal plane. 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. If a married woman has a metal contraceptive ring, it is not suitable for this examination. Adverse reactions and risks Nothing.
