What does stranding mean in a CT scan?
Fat stranding
This is a basic article for medical students and other non-radiologists. Fat stranding is a sign that is seen on CT. It describes the change in attenuation of fat around an inflamed structure and is a very helpful signpost for intra-abdominal pathology.
What is stranding on abdominal CT scan?
Summary. The observation of disproportionate fat stranding is a helpful CT sign in patients with acute abdominal pain. Anecdotally, we observed that the presence of fat stranding that is more severe than expected for the degree of bowel wall thickening suggests that the pathologic process is centered in the mesentery.
What does tissue stranding mean?
Fat stranding refers to an abnormal increased attenuation in fat, (in the mesentery, omentum, retroperitoneum, or subcutaneous fat). The underlying pathophysiologic process is increased edema and engorgement of lymphatics. Abdominal fat stranding can produce various appearances.
What is stranding in the lungs?
Atelectasis (at-uh-LEK-tuh-sis) is a complete or partial collapse of the entire lung or area (lobe) of the lung. It occurs when the tiny air sacs (alveoli) within the lung become deflated or possibly filled with alveolar fluid. Atelectasis is one of the most common breathing (respiratory) complications after surgery.
What is Strandy?
1a : fibers or filaments twisted, plaited, or laid parallel to form a unit for further twisting or plaiting into yarn, thread, rope, or cordage. b : one of the wires twisted together or laid parallel to form a wire rope or cable. c : something (such as a molecular chain) resembling a strand a strand of DNA.
Should I worry about atelectasis?
In an adult, atelectasis in a small area of the lung is usually not life threatening. The rest of the lung can make up for the collapsed area, bringing in enough oxygen for the body to function.
How do you diagnose atelectasis?
The most common test used to diagnose atelectasis is a chest X-ray. Bronchoscopy or imaging tests can confirm a diagnosis. Atelectasis treatment can include breathing or coughing exercises, inhaled medicines, breathing devices, or surgery. Atelectasis usually gets better with time or treatment.
What does Perinephric stranding indicate?
Perinephric stranding is a nonspecific sign pointing to an underlying inflammatory problem with the kidney and/or collecting system. Depending on the situation, it could result from. pyelonephritis (usually heterogeneous enhancement in the ipsilateral kidney)
What does fat attenuation mean?
The attenuation of fat as assessed with CT reflects the biochemical composition of tissue, with lower attenuation (ie, more negative numbers) corresponding to larger adipocytes and increased fat content, while higher attenuation (ie, more positive numbers) corresponding to lower lipid content and smaller adipocytes (4) …
What is Pericolic stranding?
In conclusion, pericolic fat stranding identified on CT images of colon cancer is demonstrated more frequently with increasing circumferential proportion of the tumor and longitudinal length. The presence of pericolic fat stranding suggests tumor invasion of T3 or more, but cannot distinguish between T3 and T4.
How do you fix atelectasis?
Atelectasis treatments include:
- Bronchoscopy to clear blockages like mucus.
- Medicine that you breathe in through an inhaler.
- Physiotherapy such as tapping on your chest to break up mucus, lying on one side or with your head lower than your chest to drain mucus, and exercises to help you breathe better.
What happens if atelectasis is not treated?
Atelectasis treatment can include breathing or coughing exercises, inhaled medicines, breathing devices, or surgery. Atelectasis usually gets better with time or treatment. However, if it is undiagnosed or untreated, serious complications can occur, including fluid buildup, pneumonia, and respiratory failure.
Is Perinephric fat stranding serious?
While a degree of symmetric bilateral perinephric stranding is common, particularly in the elderly, asymmetric or unilateral perinephric stranding is an important sign of renal inflammation or of acute obstruction. As such, it is seen in conditions such as acute pyelonephritis and with ureteric calculi.
What is a fatty lesion?
Fat-containing tumors are the most common soft-tissue tumors encountered clinically. The vast majority of fat-containing soft-tissue masses are benign. Lipomas are the most common benign fat-containing masses and demonstrate a characteristic appearance at magnetic resonance (MR) imaging.
Can you reverse atelectasis?
Mild atelectasis may go away without treatment. Sometimes, medications are used to loosen and thin mucus. If the condition is due to a blockage, surgery or other treatments may be needed.
What is the function of perirenal fat?
Based on these anatomical features, perirenal fat regulates the cardiovascular system presumably via neural reflex, adipokine secretion, and fat-kidney interaction.
What causes fatty tissue around the heart?
Atrial fibrillation, or a-fib, occurs when the atria (upper chambers of the heart) fibrillate (contract very fast and irregularly). A-fib is thought to be caused by inflammation and scarring (fibrosis) in the left atrium. The fat layer around the outside of the heart is called epicardial adipose tissue (EAT).
Why is there a thick layer of fat around the kidneys?
Each kidney is held in place by connective tissue, called renal fascia, and is surrounded by a thick layer of adipose tissue, called perirenal fat, which helps to protect it. A tough, fibrous, connective tissue renal capsule closely envelopes each kidney and provides support for the soft tissue that is inside.
