Comparative Diagnostic Performance of Three Commercial Real‐Time PCR Assays for the Detection of Mycobacterium tuberculosis Complex in Bronchial Washing Specimens: A Large Retrospective Study

open access: yesJournal of Clinical Laboratory Analysis, EarlyView.
This large retrospective study compared the diagnostic performance of three commercial real‐time PCR assays (AdvanSure TB/NTM, Cobas MTB, and Xpert MTB/RIF) for MTBC detection in 3348 bronchial washing specimens. In a head‐to‐head comparison of 740 specimens, the Cobas MTB and Xpert MTB/RIF assays showed markedly higher sensitivity than the AdvanSure ...

Visual Patterns of Diaphragmatic Motion in Acute Respiratory Failure: A Prospective Pilot Study

open access: yesJournal of Clinical Ultrasound, Volume 53, Issue 3, Page 421-428, March/April 2025.
In this prospective bicentric study, we studied the relationship between the appearance of diaphragmatic motion and the etiological diagnosis of patients admitted to the emergency department with ARF. We observed a different visual pattern in patients with pneumonia. This is an interesting result as it allows the diagnosis of pneumonia without the need

Study of Risk Factors and Image Findings of Isolated Abdominal Incidentally Detected Aortic Dissection

open access: yesJournal of Clinical Ultrasound, Volume 53, Issue 3, Page 429-435, March/April 2025.
We detect the risk factors and image characteristics of incidentally detected IAAD. Independent risk factors of IAAD included fatty liver and smoking. In the ultrasound findings of IAAD, an intimal flap was frequently observed. In the CT scan, displacement of intimal calcifications was frequently observed. For suspected IAAD, the abdominal aorta should

Racial and ethnic differences in hospital‐based low‐value pediatric care

open access: yesJournal of Hospital Medicine, EarlyView.
Abstract Background Low‐value care (LVC), or care in which potential risk outweighs perceived benefits, continues to impact pediatric populations. While pediatric healthcare delivery is known to vary across racial and ethnic groups, little is known about the relationship between race and ethnicity and LVC.

MRI Proton Density Fat Fraction as a Biomarker of Marrow Recovery Following Organ‐Sparing Total Marrow Irradiation in Sickle Cell Disease

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Noninvasive quantitative assessment of marrow recovery after curative therapies such as total marrow irradiation (TMI) and bone marrow transplantation (BMT) remain poorly defined, particularly in sickle cell disease (SCD). Purpose To evaluate MRI‐derived proton density fat fraction (PDFF) as a biomarker of marrow recovery following ...

Association Between MRI‐Derived Right‐to‐Left Ventricular Volume Ratio and Regional Left Ventricular Myocardial Dysfunction in Patients With Pulmonary Arterial Hypertension

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Right ventricular (RV) to left ventricular (LV) end‐diastolic volume ratio (RV/LV) is a validated marker of RV dilation in pulmonary arterial hypertension (PAH), yet its impact on LV myocardial function and the underlying mediating pathway is incompletely characterized.

5.0 T Coronary Magnetic Resonance Angiography in Calcified Coronary Arteries: Diagnostic Performance Compared With Computed Tomography Using Invasive Angiography as Reference

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Coronary computed tomography angiography (CCTA) often overestimates stenosis in calcified plaques due to blooming artifacts. The performance of 5.0 T Coronary MR angiography (CMRA) in calcified arteries remains unclear. Purpose To assess plaque effects on 5.0 T CMRA image quality and compare diagnostic performance with CCTA.

Approaches to Computed Tomography Education for Radiography Students

open access: yesJournal of Medical Radiation Sciences, EarlyView.
The aim of this narrative review was to explore the current published literature relating to CT teaching methods and assessment of diagnostic radiography students during university training. Existing CT education evaluations focus on student satisfaction and usability of tools, with post‐lesson knowledge gains reported. Future work should shift towards

Adherence to Diagnostic Imaging Pathways for Patients Presenting to Emergency Departments With Undifferentiated Acute Abdominal Pain: Impact on Radiation Exposure and Multiple Imaging Testing

open access: yesJournal of Medical Radiation Sciences, EarlyView.
There are many recommendations and guidelines when it comes to medical imaging, but just how effective and useful are they? This article examines this topic with regards to the RANZCR Imaging Pathways and acute abdominal pain. ABSTRACT Introduction The Diagnostic Imaging Pathways (DIP) are a tool that has been developed to assist physicians with ...

3D Printing a Clinically Available Solution From Plaster‐Based Positives in Superficial Radiation Therapy

open access: yesJournal of Medical Radiation Sciences, EarlyView.
This study compares two techniques for creating lead shielding masks to replace the current process for superficial/orthovoltage facial radiotherapy: Plaster Cast Positive Mould (PCPM), CT Scanned 3D Print (CT3DP), and Optical Scan 3D Print (OS3DP). CT3DP was found to be more accurate and preferred over OS3DP.
