Basics of ultrasound.

 Ultrasound is a type of imaging that uses high-frequency sound waves to look at organs and structures inside the body.

Gray scale

Gray scale is a type of ultrasound image that uses different shades of gray to show the different densities of tissue within an organ or structure.

M mode and B mode

M mode is a type of ultrasound imaging that shows how structures within the body move over time. It is often used to look at the heart and blood flow.
B mode is a type of ultrasound imaging that shows a two-dimensional image of organs and structures in the body. It is often used to look at the fetus during pregnancy, as well as other organs like the liver, kidneys, and thyroid.

Roles of Ultrasound

Ultrasound is a medical imaging technique that uses high-frequency sound waves to create images of organs and structures inside the body. It is non-invasive, safe, and painless. Ultrasound images are created by sending sound waves into the body and measuring the echoes that bounce back. These echoes are then used to create an image of the area being studied. Ultrasound is used for a variety of medical purposes, including diagnosing and monitoring pregnancy, checking for abnormalities in organs like the liver and kidneys, and guiding medical procedures like biopsies and injections.

In gynecology

Ultrasound plays a crucial role in gynecology. It is often used to diagnose and monitor conditions like ovarian cysts, uterine fibroids, and endometriosis. It is also used to monitor fetal growth and development during pregnancy. Ultrasound can be used to guide procedures like biopsies and amniocentesis. Overall, ultrasound is a safe and non-invasive way to diagnose and monitor a wide range of gynecological conditions.


Doppler ultrasound

Doppler ultrasound is a type of ultrasound imaging that is used to evaluate blood flow in the body. It uses sound waves to measure the speed and direction of blood flow through blood vessels. Doppler ultrasound is often used to diagnose conditions like deep vein thrombosis, peripheral artery disease, and carotid artery disease. It can also be used to monitor blood flow to organs like the liver and kidneys. Doppler ultrasound is safe and non-invasive, and it does not use ionizing radiation.

Details on Doppler

Doppler ultrasound is a type of ultrasound imaging that uses sound waves to measure the speed and direction of blood flow in the body. It can be used to evaluate blood flow in arteries and veins, as well as in organs like the liver and kidneys. Doppler ultrasound works by emitting high-frequency sound waves that bounce off of moving red blood cells in the bloodstream. The echoes from these sound waves are then used to create images of blood flow. Doppler ultrasound is often used to diagnose and monitor conditions like deep vein thrombosis, peripheral artery disease, and carotid artery disease. It is a safe and non-invasive imaging technique that does not use ionizing radiation.

KUB Ultrasound

Image
Ultrasound of the Kidneys In medicine, KUB refers to a diagnostic medical imaging technique of the abdomen and stands for Kidneys, Ureters, and Bladder, although in fact the Ureters only show if they are abnormally distended.  A KUB ultrasound is an examination requested by your doctor to evaluate the urinary tract (which includes the kidneys, ureters, and urinary bladder). In the male patient, the prostate gland is also scanned. A KUB Ultrasound may be requested: 1/To look for changes in the bladder wall  2/To look for changes in the kidney size or structure 3/To look for stones in the urinary tract  4/To evaluate reasons why you have recurrent kidney infection 5/To identify the cause of renal or pelvic pain  KUB Ultrasound:- The urinary bladder can only be properly assessed when full or distended, as bladder volume measurements are taken whilst the bladder is full.   The bladder and both kidneys are also scanned after the bladder has been emptied to evaluate the volume of urine ret

Deep vein thrombosis

Image
 Deep vein thrombosis  DVT stands for Deep Vein Thrombosis. It is a medical condition where a blood clot forms in one of the deep veins in the body, usually in the leg. This can cause pain and swelling in the affected area, and if left untreated, can lead to more serious health problems. In DVT, a blood clot forms in one of the deep veins in the body, usually in the leg. This can cause pain and swelling in the affected area. If the blood clot breaks off and travels through the bloodstream, it can cause a life-threatening condition called a pulmonary embolism, which occurs when the clot gets lodged in the lungs. Therefore, it is important to seek medical attention if you experience symptoms of DVT. Role of radiology in DVT Radiology plays an important role in the diagnosis and treatment of DVT. Imaging techniques such as X-rays, CT scans, and MRI scans can be used to detect blood clots and assess the severity of the condition. These imaging techniques can also be used to monitor the eff

ROLE OF CT IN EVALUATION OF ABDOMINAL MASSES

 MAIN ROLE OF CT:- An abdominal CT scan makes detailed pictures of the structures inside your belly very quickly. This test may be used to look for: Cause of blood in the urine. Cause of abdominal pain or swelling. Palpable abnormalities, such as abdominal mass or organomegaly. Both US and CT are excellent techniques for confirming or excluding the presence of an abdominal mass, with sensitivity and specificity higher than 95%. The accuracy of US in determining the organ of origin is estimated at between 88% and 91%.Mainly CT scan are 100 percent accurately in evaluation of abdominal masses. For intra-abdominal masses, contrast-enhanced CT and ultrasound examination have demonstrated accuracy. For abdominal wall masses, which may arise from muscle, subcutaneous tissue, or connective tissue, MRI, CT, and ultrasound all provide diagnostic value. An abdominal CT scan uses a special X-ray machine to take pictures of the liver, spleen, kidneys, bladder, stomach, intestines, pancreas, and ad
