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.
Abdominal ultrasound can be used to diagnose abnormalities in various internal organs, such as the kidneys, [1] liver, gallbladder, pancreas, spleen and abdominal aorta.If Doppler ultrasonography is added, the blood flow inside blood vessels can be evaluated as well (for example, to look for renal artery stenosis).
Pleurisy, also known as pleuritis, is inflammation of the membranes that surround the lungs and line the chest cavity . [1] This can result in a sharp chest pain while breathing. [ 1 ] Occasionally the pain may be a constant dull ache. [ 5 ]
Dialyzer technology initially outpaced the ability of clinicians to apply it to patients. In the 1920s, the first dialysis catheter was created using thin fragile glass tubes. Early methods required surgical incision to reach large vessels, which carried a large risk of major bleeding.
ACR Education Center – located in Reston, VA, offers specialized mini-fellowships in more than a dozen clinical areas. [3]American Institute for Radiologic Pathology (AIRP) – The AIRP conducts five courses for radiology residents and fellows, and seven categorical courses for practicing radiologists and other physicians each year in Silver Spring, MD.
Ultrasound can ablate tumors or other tissue non-invasively. [4] This is accomplished using a technique known as high intensity focused ultrasound (HIFU), also called focused ultrasound surgery. This procedure uses generally lower frequencies than medical diagnostic ultrasound (250–2000 kHz), but significantly higher time-averaged intensities.
The transducer may be used in contact with the skin, as in fetal ultrasound imaging, or inserted into a body opening such as the rectum or vagina. Clinicians who perform ultrasound-guided procedures often use a probe positioning system to hold the ultrasonic transducer. [9] Compared to other medical imaging modalities, ultrasound has several ...
The American Society of Radiologic Technologists (ASRT) is a professional membership association that serves medical imaging technologists, radiation therapists, and radiologic science students. [1] The organization, located in Albuquerque, New Mexico provides its members with ongoing education and professional development opportunities.
