Hip x-rays help screen for osteoporosis in THA patients
In this study, the group expanded on this research by investigating the correlation between indices on standardized preoperative x-rays of the hip and the proximal femoral neck T-score, measured by DEXA, in a Caucasian population with a high number of male patients.An example of measurement on plain anterior-posterior x-rays used in the study: canal-bone-ratio CBR-7 cm (Cm/Cc) and CBR-10 cm (Dm/Dc), canal-calcar ratio CCR (Dm/Bm); canal flare index CFI (A/Dm). Image courtesy of Scientific Reports.The group retrospectively analyzed results from 216 elderly male and female Caucasian patients treated with unilateral THA for p...

Machine learning in the detection of dental cyst, tumor, and abscess lesions
ConclusionThe
GLCM features can be used for further research. After improving the
performance and training, it can support routine histological diagnosis
and can assist the clinicians in arriving at accurate and spontaneous
treatment plans. (Source: Dental Technology Blog)

Four-Year Pulp Survival in a Randomized Trial on Direct Pulp Capping
ConclusionsThe
low 4-year success rates reported here challenge the concept of direct
pulp capping in the cases that were included. NaOCl lavage did not only
increase the survival of affected pulps substantially, but particularly
diminished painful failures (33% in the NaOCl group versus 62% in the
saline group). The lack of predictive value of MMP-9 assessments beyond
early treatment failures points to inflammatory states of the pulp
tissue under deep caries, which are not related to neutrophil
infiltration. (Source: Dental Technology Blog)

Road to RSNA 2023: Imaging Informatics Preview
In many respects, AI has come to dominate the field of imaging informatics research, a trend that will be evident at RSNA 2023. In this stop on the Road to RSNA, we take a look at AI as it is being tested in various imaging modalities for communication, analysis, efficiency, organization, and problem-solving. Among them are tests of the effectiveness and accuracy of large language models (LLMs) such as ChatGPT, Bard, and others. We bring you previews of comparison studies of LLMs in generating radiology reports and consumer-friendly health information to support lung cancer prevention, screening, and education. With th...

Comparison of Efficacy of Lidocaine and Articaine as Inferior Alveolar Nerve Blocking Agents in Patients with Symptomatic Irreversible Pulpitis: Randomized Controlled Trial
Conclusions: The
anesthetic efficacy of Articaine is similar to that of lidocaine in
subjects with symptomatic irreversible pulpitis. Hence, Articaine can
serve as an alternative to Lidocaine for local anesthesia administration
in dentistry. (Source: Dental Technology Blog)

Road to RSNA 2023: Digital X-Ray
This year’s trip along the Road to RSNA for digital x-ray features mileposts mostly set by AI research. Models will be proposed for applications ranging from predicting bone density on chest x-rays to generating complete reports on anterior cruciate ligament (ACL) tears. Yet several presentations to be given at the meeting reminded us that issues concerning basic elements of x-ray technology remain highly important, as well as whether imaging access is equitable in the "real-world."In one, a group at the University of Washington in St. Louis asked, “How much ionizing radiation are neonatal patients exposed to during ...
