Up to 30% of these children may develop splenic sequestration crisis with a mortality rate of up to 15%. This crisis occurs when splenic vaso-occlusion causes a large percentage of total blood volume to become trapped within the spleen. Clinical signs include severe, rapid drop in hemoglobin leading to hypovolemic shock and death.
Increased deoxygenation causes sickling of red blood cells, which adhere to the spleen wall and splenic macrophages causing ischemia. [2] This ischemia can result in splenic sequestration, where large amounts of blood pool in the spleen but do not flow within vasculature. [11]
This examines for free fluid around the kidney and liver. Left Upper Quadrant of the abdomen (Perisplenic view). Left upper quadrant is examined by working your probe down the midaxillary line starting at the left 8th rib to the 11th rib. This examines for free fluid around the kidney and spleen. Pelvic views (Long and transverse axis).
Myelography is a type of radiographic examination that uses a contrast medium (e.g. iodised oil [1]) to detect pathology of the spinal cord, including the location of a spinal cord injury, cysts, and tumors.
Spinal cord injury without radiographic abnormality (SCIWORA) is symptoms of a spinal cord injury (SCI) with no evidence of injury to the spinal column on X-rays or CT scan. [4] [5] Symptoms may include numbness, weakness, abnormal reflexes, or loss of bladder or bowel control. [2]
Radiation from orthovoltage x-ray machines has been called "deep" due to its greater penetrating ability, allowing it to treat tumors at depths unreachable by lower-energy "superficial" radiation. Orthovoltage units have essentially the same design as diagnostic X-ray machines and are generally limited to photon energies less than 600 keV.
G-arm medical imaging systems are based on fluoroscopic X-ray and are used for a variety of diagnostic imaging and minimally invasive surgical procedures.The name is derived from the G-shaped arm used to connect two X-ray generators and two X-ray detectors, image intensifiers or digital flat panel detectors, to one another.
EOS is a medical imaging system designed to provide frontal and lateral radiography images, while limiting the X-ray dose absorbed by the patient in a sitting or standing position.
