SWE and TENDINOPATHY

Shear-wave elastography aids monitoring of tendinopathy

By Erik L. Ridley, AuntMinnie staff writer

December 15, 2015 -- Shear-wave elastography performs better than B-mode and power Doppler ultrasound for evaluating tendinopathy and helping to assess treatment response, German researchers recently reported at the RSNA 2015 meeting in Chicago.

Not only was shear-wave elastography more sensitive for detecting tendinopathy in a prospective study, but the technique's quantitative data had much higher correlation with clinical examination scores, according to presenter Dr. Timm Dirrichs of University Hospital RWTH Aachen in Aachen, Germany

LIVER ELASTOGRAPHY IN THE PREDICTION OF THE PRESENCE OF HCC

LIVER ELASTOGRAPHY IN THE PREDICTION OF THE PRESENCE OF HCC

Prognosis of patients with chronic liver disease is determined by the extent and progression of liver fibrosis, which may lead to the development of HCC. Liver stiffness is significantly higher in patients with HCC than in patients without HCC. However, most of the studies found that liver stiffness alone is insufficient to predict the presence or absence of HCC and that it should be associated in a score with other markers. A score developed by Wong et al based on liver stiffness, age, serum albumin and hepatitis B virus DNA level was found to have AUROC’s of 0.83 to 0.89 in the identification of the HCC patients and a very good negative (99.4%-100%) for the exclusion of HCC in patients. In the study conducted by Feier et al, LS was significantly higher (42 kPa vs 27 kPa, P < 0.0001) in the HCC group than in the non-HCC group, but other 3 parameters (alanine-aminotransferase, alphafetoprotein and interquartile range of the LSMs) were added to elastography in a score and the resulted model combining the four variables showed a good diagnostic performance in both training and validation groups, with AUROCs of 0.86 and 0.8, respectively. Jung et al has shown that liver stiffness is also useful as a part of a predictive model that identifies patients that are at risk for late recurrence after curative resection of HCC. On multivariate analysis, patients with older age, male sex, heavy alcohol consumption (> 80 g/d), lower serum albumin, HBe antigen positivity and LSM> 8 kPa were at a significantly greater risk of HCC development.

SMI on Toshiba Aplio 500

Superb Micro-Vascular Imaging (SMI) is an innovative ultrasound Doppler technique developed by Toshiba. SMI offers a unique algorithm that allows visualization of microvasculature with low velocity but without using any contrast agents.

 The advantages of SMI include 
 1) low velocity flow visualization, 
 2) high resolution 
 3) minimal motion artefact, and
 4) high frame rates. The exceptional vessel detection ability allows SMI to be of benefit in the evaluation and treatment of liver diseases. 

SMI has potential in:
 i. Display of minute intra-lesional vasculature
 ii. Evaluating RFA treatment
 iii. Support RFA planning and guiding.

Advanced Applications

Superb Micro-Vascular Imaging (SMI)*

Toshiba's innovative Superb Micro-Vascular Imaging (SMI) technology expands the range of visible blood flow and provides visualization of low velocity microvascular flow never before seen with ultrasound. SMI's level of vascular visualization, combined with high frame rates, advances diagnostic confidence when evaluating lesions, cysts and tumors, improving patient outcomes and experience. Improve Accuracy and Speed with SMI Getting accurate diagnostic information faster is just one reason why Toshiba’s Superb Micro-Vascular Imaging (SMI) is an integral part of operations for our partners at Rex Healthcare.
