The renal fascia separates the adipose capsule of kidney from the overlying pararenal fat. The deeper layers deep to the renal fascia are, in order, the adipose capsule (or perirenal fat), the renal capsule and finally the parenchyma of the renal cortex. [2] At the renal hilum, the renal capsule extends into the renal sinus. [1]
The kidney is surrounded by a capsule separating the kidney from the echogenic perirenal fat, which is seen as a thin linear structure. [1] The kidney is divided into parenchyma and renal sinus. The renal sinus is hyperechoic and is composed of calyces, the renal pelvis, fat and the major intrarenal vessels.
The renal capsule surrounds the functional tissue of the kidney, and is itself surrounded by a fatty adipose capsule, fascia, and fat. From the inner part of the kidney to outside the kidney, the positioning of the capsule is: renal medulla; renal cortex; renal capsule; adipose capsule of kidney (or perirenal fat, or perinephric fat) renal fascia
Perirenal fat (also "perirenal fat capsule", "perinephric fat, [5] or "adipose capsule of the kidney" [6]) is external to the fibrous capsule of the kidney, and internal to the renal fascia (which separates it from the pararenal fat); connective tissue trabeculae extend through it to unite the fibrous capsule of the kidney, and the renal fascia ...
to provide a high contrast image of the details of the viscera under study; e.g. salts of heavy metals, gas like air, radio-opaque dyes, organic iodides, etc. Echocardiography machine: sonography of the heart is done here to know its function and state Computer axial tomography scan /(CAT Scan)
Radiology [ edit ] A magnetic resonance imaging (MRI) scan may be used to identify the collection of blood, although this is often not performed if bleeding is a medical emergency .
Fat in tumors such as in adrenocortical adenomas; Fat-stranding as seen in inflammation such as appendicitis, diverticulitis and omental infarction; Pulmonary arterial phase 6-13 sec [6] - Pulmonary embolism (can use bolus tracking in pulmonary trunk + 6 seconds) [7] Pulmonary venous phase 17-24 sec [6]-Early systemic arterial phase 15-20 sec ...
Fat suppression is an MRI technique in which fat signal from adipose tissue is suppressed to better visualize uptake of contrast material by bodily tissues, reduce chemical shift artifact, and to characterize certain types of lesions such as adrenal gland tumors, bone marrow infiltration, fatty tumors, and steatosis by determining the fat content of the tissues.
