Magnetic resonance is a relatively accurate examination for kidney diseases. It can observe images of the coronal, transverse and sagittal planes of the kidneys, and display the blood flow rate, anatomical structure and chemical composition of the kidneys. The scope and nature of renal lesions can be roughly determined by MRI, but some renal diseases, such as interstitial nephritis, are usually not examined using MRI.
Magnetic resonance has certain indications for the examination of renal diseases, mainly including mass examination, infection examination, trauma examination, vascular assessment, diffuse substantial lesion examination, and malformation examination.
MRI can be categorized into plain scan and enhanced scan, in which enhanced scan requires injection of contrast agent, which is toxic to renal tubules, and MRI enhanced scan is generally not recommended for people with interstitial nephritis and tubular damage.
Magnetic resonance is more accurate for most renal diseases, but in order to further clarify the cause of the disease, on the basis of this examination, renal function tests, renal ultrasound, renal pathology can also be carried out in conjunction with the examination.
Patients with impaired renal function are recommended to visit regular hospitals in time, complete relevant examinations under the guidance of physicians to clarify the condition and carry out targeted treatment.
