A universal phantom suitable for quality assurance on X-ray imaging modalities.

CONCLUSION: It may be concluded that the U-QA phantom, with accompanying data analysis software and user's manual, offers an acceptable single phantom solution for medical X-ray imaging. It is a cost and time saver and could therefore fill a gap in the existing market. The phantom could also be used by radiographers in resource-limited institutions.

[Digital volume tomography : Dedicated scanner and cone beam CT with C‑arm systems]. Radiologe. 2018 Feb 07;: Authors: Fiebich M, Weber D Abstract CLINICAL/METHODICAL ISSUE: Digital volume tomography (DVT) and cone-beam computed tomography (CT) with C‑arm systems have become established three-dimensional imaging systems as an alternative to CT in some application areas. STANDARD RADIOLOGICAL METHODS: The technology of the systems is well developed so that they have become a competing method to CT imaging in terms of image quality and radiation exposure. PERFORMANCE: An advantage is ...

In readinglast year's RSNA report, I was struck with just how little has changed.Here I am this year, 2017, and here's how I looked at RSNA 2016:A little grayer, perhaps a pound or two more. But otherwise same ol'Dalai. And same ol'RSNA. I even manned the RAD-AID booth again:Yes, I tied the bow-tie all by myself.This is a model housed at the Bayer booth of the airship RAD-AID hopes to use to bring imaging to underserved areas; I think the official rendering is much more impressive, and maybe even a little, well,buxom:I'm still lobbying for a seat on the first flight. Did I saybuxom? I meanthandsome!I did attend the requisi...

This study summarizes and compares estimates of radiation absorbed dose to the thyroid gland for typical patients who underwent diagnostic radiology examinations in the years from 1930 to 2010. The authors estimated the thyroid dose for common examinations, including radiography, mammography, dental radiography, fluoroscopy, nuclear medicine, and computed tomography (CT). For the most part, a clear downward trend in thyroid dose over time for each procedure was observed. Historically, the highest thyroid doses came from the nuclear medicine thyroid scans in the 1960s (630 mGy), full-mouth series dental radiography (390 mGy...

What if an algorithm could tell you whether you have cancer based on your CT scan or mammography exam? While I am certain that radiologists’ creative work will be necessary in the future to solve complex issues and supervising diagnostic processes; AI will definitely become part of their daily routine in diagnosing simpler cases and taking over repetitive tasks. So rather than getting threatened by it, we should familiarize with how it could help change the course of radiology for the better. Radiologists who use AI will replace those who don’t There is a lot of hype and plenty of fear around artificial intelli...

Diagnostic X-ray imaging depends on the maintenance of image quality that allows for proper diagnosis of medical conditions. Maintenance of image quality requires quality assurance programs on the various X-ray modalities, which consist of pro ­jection radiography (including mobile X-ray units), fluoroscopy, mammography, and computed tomography (CT) scanning. Currently a variety of modality-specific phantoms are used to perform quality assurance (QA) tests. These phantoms are not only expensive, but suitably trained personnel are needed to successfully use them and interpret the results. The question arose as to whethe...

This study provides the first direct evidence that CT scanning and nuclear medicine examinations are associated with an increased risk of thyroid cancer. The novel finding that an array of diagnostic radiography procedures are associated with thyroid microcarcinomas warrants further investigation.

Although approximately 70% of breast cancer patients demonstrate a clinical response on neoadjuvant systemic therapy on physical examination or on anatomic radiographic imaging, only 3%–40% achieve a pathologic complete response (pCR). Magnetic resonance imaging (MRI) is superior to physical examination, ultrasound, and mammography in response evaluation during neoadjuvant systemic therapy. The accuracy of breast MRI to predict pCR has a moderate sensitivity, but high specificity. The accuracy of anatomic imaging to assess residual disease and predict pCR depended on anatomic radiographic imaging cancer subtypes. Res...
