Road to RSNA 2017: Ultrasound Preview

Nov 7, 2017

By Kate Madden Yee, Editor 

Dear AuntMinnie Member,

At the upcoming RSNA 2017 meeting in Chicago, you'll hear variations on the key theme of how ultrasound in its various forms helps clinicians diagnose disease, stage treatment, and track healing. Technologies under discussion will range from shear-wave elastography and contrast-enhanced ultrasound (CEUS) to MRI-guided high-intensity focused ultrasound, just to name a few.

Researchers will address a variety of clinical questions. How well does ultrasound correlate to MRI findings of suspicious lesions? How well do guidelines from the Society of Radiologists in Ultrasound define cirrhosis? Does ultrasound reduce complications in pediatric renal biopsies? And can the technology help assess the effectiveness of compression stockings to prevent delayed-onset muscle soreness? (Spoiler alert: Yes.)

Look for research that explores the use of contrast ultrasound to assess muscle injuries and hepatic artery blocks and to diagnose Crohn's disease recurrence, as well as discussion of how real-time elastography can detect "golfer's elbow"; a new technique that registers ultrasound and MRI data to help guide spine needle interventions; and whether photoacoustic ultrasound is an effective alternative to fine-needle aspiration biopsy of the thyroid.

As for breast imaging, presenters will investigate studies on everything from how screening ultrasound compares with digital breast tomosynthesis and mammography and whether real-time breast ultrasound after a second opinion can prevent unnecessary biopsies to the effect of deep-learning software on the modality's performance.

Need to up your ultrasound game? At RSNA 2017 you'll find courses that address a range of topics, including diagnosing, tracking, and treating thyroid cancer; interventional breast procedures; musculoskeletal ultrasound; vascular Doppler; and interventional sonography.

Finally, check out the RSNA's controversy session on pelvic imaging -- "When is ultrasound enough?" -- as well as sessions on emerging uses of the technology (think immuno-imaging probes and elastography) and a primer on how to integrate CEUS into radiology practice.

For highlights of some of the many ultrasound scientific sessions and posters scheduled for presentation at this year's meeting, read on. To view the RSNA's complete listing of abstracts for this year's scientific and educational program, click here.



Echo Research and Practice journal

Nov 1, 2017

The journal, Echo Research and Practice (ERP)with whom we share significant content interest, is currently being considered for indexing in Web of Science’s Science Citation Index Expanded (SCIE). Indexing in SCIE is required in order to obtain anImpact Factor, an important step in the development of any new journal.

The publication expects to receive a decision between December 2017 and March 2018. The number of citations to articles published in ERP will be critical in the decision making process. The publishers have asked for ICUS's help at this critical time by promoting the journal to our members and colleagues. The more people are aware of the journal and access its content the more citations it is likely to obtain ultimately.

If you use Twitter, the journal would very much appreciate you highlighting some of the content published in ERP to your networks. It also has a number of important conferences coming up, including the BSE Annual Meeting and EuroEcho Imaging, and will be raising the profile of the journal at both of these.



Latest Advancements in Radiology and Imaging

Oct 25, 2017

By Dr. Sudheer Pargewar ,Consultant-Diagnostic & Interventional Radiology, Global Hospitals, Mumbai

Radiology has come a long way since the discovery of X-rays in 1895 by German physicist Wilhelm Roentgen, and now plays an indispensable role in improved and better diagnosis and patient monitoring. The ever evolving stream of radiology, besides X-rays, further encompasses remarkable advances in various other modalities including ultrasonography (USG), Computed Tomography (CT scan), Magnetic Resonance Imaging (MRI) and Mammography. Furthermore, imaging guidance is now widely used for minimal invasive treatment of various medical conditions.

One of the major transitions being now adopted by many hospitals across the country is ‘going paper-less’ and the Picture Archive and Communication System (PACS) and Radiology Information System (RIS) are a giant step in this direction. Radiologists use the PACS to store the multitude of image files which can be easily retrieved at any course of time in the patient management. Thus, the entire database of images of all patients across all modalities is just a click away, saving time in locating and managing the hard copies. With the help of software solutions like RIS, it is now possible to keep a track record of every patient from scheduling appointments to diagnosis and treatment. With the digitalization of medicine, radiology data sharing is now eased out with the use of Digital Imaging and Communications in Medicine (DICOM).

The traditional X-ray films are now virtually replaced by the Computed Radiography (CR) and Digital Radiography (DR) panels with both of these having the advantage of being shared across multiple systems. Furthermore, a DR system requires less space as it obviates the need for installing the bulky CR cassette reader and also is much faster than a CR or film, with the captured image being almost instantly transferred to the workstation. In the interventional radiology (IR) suites, the versatile flat-panel computed tomography (FPCT) or flat panel volume tomography provides wide areas of coverage in each rotation provides dynamic real-time data with high spatial resolution.

Advances in breast imaging for screening and timely detection include the use of 3D Digital Breast Tomosynthesis (DBT) which reduces the overlap by normal breast tissue and has a 25-50% better mass detection rate vis-à-vis a 2D mammogram. Additionally, 3D-Automated breast ultrasound (ABUS) units are coming up to overcome the problem of screening dense breasts in young women with mammography. Mammography, USG as well as MRI guided Vacuum-assisted biopsies (VAB) may be performed for both diagnosis and treatment of small lesions.

A newer technology in USG includes the sonoelastography useful in measuring the tissue stiffness and thus finds application in staging liver fibrosis, characterization of indeterminate thyroid nodules, breast lump and lymph-nodes. Another advancement is the availability of ultrasound contrast agents, which like CT and MRI, helps in better tumor detection, particularly useful in patients with deranged renal function when CT and MRI are contraindicated. Fusion imaging (USG with CT/MRI) where images move synchronously in the same plane allow for better lesion localization while performing USG guided biopsies and ablation procedures.

CT scanners are now going further higher beyond the 64-slice with vendors offering 128-, 256-, 320- and 640- slice systems with the newer detector technology reducing scan times, radiation doses and increasing signal-to-noise ratio. Particularly useful now is non-invasive cardiac CT wherein faster scanning eliminates the need for invasive diagnostic catheter angiographies. Spectral CT (dual source or dual energy CT) helps in chemical analysis by scanning at different energies in a single scan and thus can be used to analyse kidney stones, reduce metal artefacts, diagnose gout crystals, to name a few applications.

MRI has matured further with the advent of 7T scanners and higher, improving acquisition speeds and availability of applications like functional MRI (fMRI) and diffusion tensor imaging (DTI) in neurology, cardiac MRI, time-resolved contrast-enhanced angiography, MRI enteroclysis and MR Elastography (MRE) for liver fibrosis scoring. Intraoperative MRI suites (IMRIS) allow for immediate post-operative assessment of surgical bed, without the need to mobilize the anaesthetized patient.

There is definitely more to come! And with rapid advances in each imaging modality day-by-day, the diagnosis and patient care stands to be revolutionized, faster and better.
