MRI of adrenal glands

The sensitivity and specificity of MRI in the diagnosis of adrenal pheochromocytoma is higher than that of CT. It is conducive to the diagnosis of adrenal diseases according to the tissue characteristics changed by the strength of the signal. Basic Information Specialist classification: Urological examination classification: Nuclear magnetic resonance Applicable gender: whether men and women apply fasting: fasting Tips: Please relax when checking. Normal value Indications 1. Functional adrenal lesions (1) Primary aldosteronism. (2) pheochromocytoma. (3) Cortisol. A, adrenal hyperplasia. B, adrenal adenoma. 2. Non-functional adrenal lesions (1) Non-functional adenomas. (2) Metastasis. (3) cysts. (4) Myeloid lipoma. Clinical significance (1) MRI contrast resolution is better than CT, available for 3D images, no ionizing radiation. The tissue characteristics that can be changed according to the strength of the signal are conducive to the diagnosis of adrenal diseases. (2) MRI diagnosis of adrenal pheochromocytoma is more sensitive and specific than CT. (3) Applying changes in the strength of different sequence signals, it can be judged whether there is necrosis, cystic change or hemorrhage in the tumor. High results may be diseases: Adrenal medulla hyperfunction, adrenal crisis precautions 1. It is difficult to judge adrenal hyperplasia and microscopic tumors simply by using mr. It is necessary to combine other imaging examinations. 2. The qualitative diagnosis and therapeutic effect of adrenal neuroblastoma can be traced by 31p spectroscopy. 3, adrenal mass should be associated with portal vein hypertension caused by splenic vein bending, dilation and spleen nodules or parasplem identification. Inspection process MRI examination. Not suitable for the crowd It is not advisable for pregnant and lactating women to perform this test. Adverse reactions and risks Generally no adverse reactions.
