Multispiral computed tomography (MCT) of the kidneys is a method of layering the organ in the axial plane, followed by the construction of reconstructions in different planes. On modern multi-detector tomography scanners, the cut thickness is 0.5 to 1 mm, which allows to reveal small details of parenchimate and renal sinus. Subsequent construction of multiplanary and voluminous 3D reconstructions gives an overall picture of the kidney’s condition.
The standard method of ICST kidneys includes native study (without intravenous contrast) and study after the pain intravenous injection of the contrasting drug in the arterial, parenchimate, excretory and, if necessary, delayed phase.
The diagnostic capabilities of ICST combine the possibilities of ultrasound,review X-rays of the kidney and ureter area, EW, RUPG, renal angiography and retropneumoperitonum research. MICT kidneys provides information about the ratio of kidneys and ureters to bone landmarks and surrounding organs, the condition of parenchyma, excretory system, ratio of the thickness of parenchyma and excretory system, the state of paranephral fat and lumbar muscles, as well as the features of the functioning of the kidney.
Extensive diagnostic capabilities of ICST determine the indications for its use, namely: the diagnosis of acute and chronic inflammatory diseases with the establishment of their variant, stage, complications; diagnosis of congenital abnormalities of kidney and ureter development; diagnosis and differential diagnosis of benign and malignant kidney tumors, staging of the tumor process; diagnosis of urinary stone disease with prediction of the results of lithotripsy on densitometric density of stone; diagnosis of vasorenal conflict in patients with hypertension; establishing the nature and extent of traumatic kidney changes.
The study is easily tolerated by patients, does not require special training, is not contraindicated only in pregnancy and intolerance of iodine drugs.
