The sign is an imaging finding using a 3.5–7.5 MHz ultrasound probe in the fourth and fifth intercostal spaces in the anterior clavicular line using the M-Mode of the machine. This finding is seen in the M-mode tracing as pleura and lung being indistinguishable as linear hyperechogenic lines and is fairly reliable for diagnosis of a pneumothorax.
The diagnosis of retroperitoneal fibrosis cannot be made on the basis of the results of laboratory studies. CT is the best diagnostic modality: [25] a confluent mass surrounding the aorta [6] and common iliac arteries can be seen. On MRI, it has low T1 signal intensity and variable T2 signal.
Retroperitoneal bleeding is an accumulation of blood in the retroperitoneal space. Signs and symptoms may include abdominal or upper leg pain , hematuria , and shock . It can be caused by major trauma or by non-traumatic mechanisms.
The imaging occurs real-time and without sedation, so that the influence of movements can be assessed quickly. For example, by pressing the ultrasound probe against the gallbladder, a radiological Murphy's sign can be elicited. Through the abdominal wall, organs inside the pelvis can be seen, such as the urinary bladder or the ovaries and ...
Bleeding from a blood vessel or structure in the retroperitoneal such as the aorta or inferior vena cava into the retroperitoneal space can lead to a retroperitoneal hemorrhage. Retroperitoneal fibrosis; Retroperitoneal lymph node dissection; It is also possible to have a neoplasm in this area, more commonly a metastasis; or very rarely a ...
Doppler ultrasonography is medical ultrasonography that employs the Doppler effect to perform imaging of the movement of tissues and body fluids (usually blood), [1] [2] and their relative velocity to the probe. By calculating the frequency shift of a particular sample volume, for example, flow in an artery or a jet of blood flow over a heart ...
The retroperitoneum or retroperitnium is an anatomical region that includes the peritoneum-covered organs and tissues that make up the posterior wall of the abdominal cavity and the pelvic space - which extends behind to the abdominal cavity.
