Under what circumstances should a pelvic MRI be performed?

Conditions that may require a pelvic MRI generally include screening for pelvic tumors, evaluating gynecological diseases, diagnosing urinary system abnormalities, assessing pelvic floor dysfunction, and assisting in the formulation of tumor treatment plans. Specific details are as follows:

1. Screening for pelvic tumors: When an abnormal mass of unknown nature is detected in the pelvis, or when symptoms such as pelvic pain or abnormal bleeding raise suspicion of a tumor, pelvic MRI can clearly show the size, location, and relationship of the mass to surrounding tissues, helping determine whether the mass is benign or malignant, thus providing critical information for further diagnosis.

2. Evaluating gynecological conditions: For gynecological disorders such as uterine fibroids, ovarian cysts, and endometriosis, pelvic MRI provides precise imaging to assess the extent and severity of the disease. It also helps determine surgical suitability and evaluate surgical complexity, thereby assisting physicians in developing appropriate treatment strategies.

3. Diagnosing urinary system abnormalities: When experiencing unexplained symptoms such as frequent urination, urgency, or painful urination, or when there is suspicion of bladder tumors, ureteral obstruction, or prostate lesions (in men), pelvic MRI can clearly visualize the structures of the urinary system, helping to identify the location and nature of the pathology.

4. Assessing pelvic floor dysfunction: In cases of stress urinary incontinence, pelvic organ prolapse, or other pelvic floor dysfunctions, pelvic MRI can dynamically observe the morphology and function of pelvic floor muscles and ligaments, evaluate the degree of damage, and provide valuable information for planning rehabilitation or surgical interventions.

5. Assisting in tumor treatment planning: For patients already diagnosed with pelvic tumors (such as cervical cancer or rectal cancer), pelvic MRI is essential before treatment to determine the tumor stage and check for metastasis. After treatment, regular MRI follow-ups are needed to monitor for tumor recurrence and assess therapeutic response.

When undergoing a pelvic MRI, it is important to choose a reputable medical institution. Prior to the scan, patients should remove all metal objects as instructed by their healthcare provider.
