Peripheral Arterial Doppler Ultrasonography: Diagnostic Criteria

Journal of Ultrasound in Medicine, 1992
Fifty-one patients (86 legs) were studied from the aorta to the popliteal artery with both duplex ultrasonography and arteriography with the intention of establishing diagnostic ultrasonographic criteria for degrees of stenosis greater than 50% and determining the effect of multi-segment disease on the accuracy of these criteria.

Musculoskeletal Ultrasonography Assists the Diagnostic Performance of the 2010 Classification Criteria for Rheumatoid Arthritis

Modern Rheumatology, 2013
We investigated whether musculoskeletal ultrasonography (MSKUS) assists the diagnostic performance of the 2010 rheumatoid arthritis (RA) classification criteria.Sixty-nine early arthritis patients were consecutively enrolled. None of the patients had been treated.

Major Salivary Gland Ultrasonography in the Diagnosis of Sjögren’s Syndrome: A Place in the Diagnostic Criteria?

Rheumatic Disease Clinics of North America, 2016
Major salivary gland (SG) ultrasonography (US) represents a noninvasive, nonirradiating imaging modality for evaluation of the major SGs in the diagnosis and follow-up of primary and secondary Sjögren syndrome. Structural changes can be visualized as hyperechogenic and hypoechogenic areas, inhomogeneity, and altered echogenicity in general.

Cranial Doppler ultrasonography correlates with criteria for ventriculoperitoneal shunting

Surgical Neurology, 1989
Using pulsed Doppler ultrasound through the sonic window of the anterior fontanelle in infants, 46 children with ventriculomegaly had sequential evaluations of Resistive Index for comparison with the need for ventriculoperitoneal shunting. Hydrocephalus was associated with myelomeningocele in 17 patients and posthemorrhagic, postmeningitic, or ...

Doppler ultrasonography criteria of superior mesenteric artery stenosis

Journal of Clinical Ultrasound, 2019
AbstractPurposeThe techniques mostly used for the diagnosis of superior mesenteric artery (SMA) stenosis are computed tomography angiography (CTA), and magnetic resonance angiography. We aimed to evaluate color‐coded Doppler Ultrasonography (CDUS) for the detection of SMA stenoses and to determine Doppler criteria.MethodsWe identified retrospectively ...

Ultrasonography of the Normal Pancreas

Radiology, 1977
Study of 135 ultrasonograms shows that it is possible to display the normal pancreas with 82% success. The pancreatic head ranges between 11 and 30/mm/in thickness, the isthmus 4-21 mm in thickness, and the corporeo-caudate area 24-32 mm in thickness. The pancreas may have a sausage, dumb-bell, or tadpole shape.

Scientifically based safety criteria for ultrasonography

Journal of Ultrasound in Medicine, 1992
One of the major contributions of E. L. Carstensen to medical ultrasonography lies in the research studies by him and his colleagues on biophysical mechanisms for biological effects. These studies have done much to provide a basis for predicting conditions under which ultrasound will affect living systems.

Criteria and scheduling of quality control of b‐mode and doppler ultrasonography equipment

Journal of Clinical Ultrasound, 2012
AbstractPeriodic quality control (QC) for ultrasound scanners checks their overall performance, reducing the risk of inaccurate diagnoses. Data from routine annual QC activity were analyzed to optimize the scheduling and the criteria of further QC programs.
