Objective: Radiology reporting is an essential component of clinical diagnosis and decision-making. With the advent of advanced artificial intelligence (AI) models like GPT-4 (Generative Pre-trained Transformer 4), there is growing interest in evaluating their potential for optimizing or generating radiology reports. This study aimed to compare the quality and content of radiologist-generated and GPT-4 AI-generated radiology reports.

However, radiomics has the potential to characterize renal masses without the need for invasive procedures. Here, we conducted a systematic review on the accuracy of CT radiomics in distinguishing fp-AMLs from RCCs.

An experimental, regional ultra-high resolution CT scan identified an additional volume of cysts relative to standard chest CT imaging, which consisted primarily of ultra-small cysts.
Research Question: What is the impact of these ultra-small cysts on the pulmonary function of patients with LAM?
Study Design And Methods: A group of 103 patients with LAM received pulmonary function tests and a CT examination in the same visit.
In this research, carboxyl-terminated hyperbranched poly(amidoamine) dendrimers grafted superparamagnetic nanoparticles (CT-HPMNPs) with core-shell structure were synthesized by the chemical co-precipitation method, the core of superparamagnetic iron oxide nanoparticles and a shell of polyamidoamines (PAMAM) and carboxyl groups, as a novel adsorbent for removing Hg from aqueous systems. The surface of the particles was modified by 3-(aminopropyl) triethoxysilane, and finally, PAMAM and carboxyl dendrimers were grown on the surface up to 5.5 generation.

In cystic lung diseases, cyst score is derived from CT scans and defined as the percentage of the total lung parenchymal volume occupied by cysts, a biomarker which measures the severity of the disease.
Methods: In a prospective study of 73 LAM patients, each patient received the standard HRCT chest scan and a short z-length UH re-scan.
In the present research, a zinc oxide (ZnO)-silver (Ag)-neodymium (Nd) nanocomposite was synthesized via the combustion method for the degradation of dyes as organic pollutants. The synthesized nanophotocatalyst was characterized using X-ray diffraction, Fourier transform infrared spectroscopy, and scanning electron microscopy techniques. The process of organic pollutant (Acid Red 18) removal was carried out in a semi-batch photoreactor equipped with an ultraviolet lamp.

This novel functionalized graphene oxide was characterized thoroughly by FTIR, XRD, FE-SEM, TEM, and TG-DT analyses. GO-GAA was then employed as an adsorbent for Hg(2+) removal from aqueous solutions.

BIVADs provide mechanical support for ventricular ejection in the failing heart and have become an accepted treatment for end-stage heart failure. They also have proved to be a successful bridge to heart transplantation.

A workshop/symposium on “Mucociliary and Cough Clearance (MCC/CC) as a Biomarker for Therapeutic Development” was held on October 21–22, 2008, in Research Triangle Park, NC, to discuss the methods for measurement of MCC/CC and how they may be optimized for assessing new therapies designed to improve clearance of airway secretions from the lungs. The utility of MCC/CC as a biomarker for disease progression and therapeutic intervention is gaining increased recognition as a valuable tool in the clinical research community. A number of investigators currently active in using MCC/CC for diagnostic or therapeutic evaluation presented details of their methodologies.

Deposition distribution variability strongly influences data from radioaerosol mucus clearance measurements. We investigated how one clearance measurement-the area under the 0-6 h tracheobronchial retention curve (AUC)-relates to three different indices characterizing initial particle distribution. These indices were a conventional penetration index (PI), retention at 24 h (R(24)) and an Airways Penetration Index (API).

Background: Complementary and alternative medicine have become an increasingly topical theme in respiratory medicine. Aromatics are a commonly used ingredient in a number of proprietary medicines. It is well established that lung mucus clearance is impaired in patients with chronic airways obstruction.
