“…On the other hand, all bright fluid with fat suppression (T2 or PD weighted) sequences in oblique coronal planes fully matched the standards of the ACR. Several studies from different countries other than the USA encourage using the same ACR practice parameters [ 24 , 25 , 27 , 28 ].…”

Magnetic resonance imaging (MRI) is essential for assessing shoulder conditions. This study aimed to evaluate current shoulder MRI practices in Jordan, including technical parameter patterns, and determine if they adhere to the American College of Radiology (ACR) guidelines. The retrospective analysis included data from 48 eligible participants from 13 MRI centers in March 2021. Descriptive and correlation data analysis were performed using IBM SPSS statistics version_20 and Excel 2013. Most MRI centers (50%) were private outpatient clinics with closed MRI machines above 1 Tesla. Most participants (62.5%) were male, and shoulder pain (47.9%) was the main clinical indication. Most shoulder orientations (68.7%, 33/48) were right shoulders, and the coronal MRI planes (43%, 121/280) were the most common. The alignment percentage for the axial plane was 100%, but MRI artifacts of the shoulder were present in 8.2% of cases (23/280). Dark fluid T1-W coronal sequence was not conducted in 25% of the cases. The percentage of the field view (FOV) within ACR recommendations was 45% (126/281), and slice thickness parameters were 96% (269/281). The recommended pixel area for all sequences was 47.9% (134/280), encompassing all axial, sagittal oblique, and coronal planes. However, crucial parameters, such as FOV and slice thickness, were inadequate and did not meet the ACR guidelines, resulting in suboptimal image quality of shoulder MRI. To improve MRI image quality, it is recommended that MRI technologists receive ongoing education and training on appropriate MRI image parameters.

“…The sensitivity of MR signals to a variety of tissue factors allows for the acquisition of detailed information. MRI is the best imaging method for evaluating the cerebrum/skull, and cardiovascular activities, in addition to the digestive organs, blood vessels, skeletal system, and abdomen because of its outstanding soft-tissue contrast [1,2].…”

This study is a comparison of three commonly used magnetic resonance imaging (MRI) pulse sequences to examine the image quality of the pulse sequences at a short acquisition time. Two tissue-equivalent gels were created. While one gel is constructed of polysaccharide and agarose, the other is made of ferrous benzoic xylenol orange (FBX). FBX gel is exposed to a 25 Grey dosage of 6MV photons from a linear accelerator. Repetition time (TR) was used to conduct experimental modifications in imaging parameters. The quantitative analysis comprises the signal-to-noise ratio (SNR) and contrast-to-noise ratio (CNR). Fast Spin Echo (FSE) and Fast Fluid Attenuated Inversion Recovery (FLAIR) are most comparable in SNR at 1.5 Tesla for various TR values. Conventional Spin Echo (CSE) has a CNR that is 143% and 93% higher than FSE and FLAIR, respectively. The time difference between CSE and FSE is 6 minutes and 34 seconds, whereas CSE and FLAIR is 6 minutes and 43 seconds. FSE and FLAIR provide superior image quality with quicker acquisition, suitable for patients sensitive to longer scan durations. Meanwhile, CSE stands out, delivering significantly enhanced contrast and SNR in T2-weighted images compared to other MRI pulses.

Objetivo: Comparar los hallazgos radiológicos mediante tomografía computarizada (TC) torácica en pacientes con COVID-19 en diferentes fases de la enfermedad y evaluar la reproducibilidad de un score radiológico visual para estimar la extensión de la afectación pulmonar. Métodos: Se evaluaron retrospectivamente las tomografías computarizadas de tórax de 182 pacientes con RT-PCR positiva para SARS-CoV-2. En función del tiempo de evolución de la infección, los pacientes fueron clasificados en tres grupos/estadios: fase precoz (0-4 días), intermedia/progresiva (5-9 días) y avanzada (≥10 días). Se analizó la frecuencia de cada hallazgo radiológico, así como el patrón, la apariencia y la distribución predominantes de la afectación pulmonar. La extensión de la afectación pulmonar se estimó para cada lóbulo pulmonar y para el volumen pulmonar total mediante un score tomográfico visual (rango 0-25). Resultados: El hallazgo tomográfico predominante fue el patrón en vidrio deslustrado (n = 110, 60,4%), la distribución más frecuente, la periférica (n = 116, 66,7%) y la apariencia más prevalente, la típica (n = 112, 61,5%). El “signo del halo” se encontró más frecuentemente en la fase precoz (25%), mientras que las opacidades en vidrio deslustrado, el patrón en empedrado y las líneas subpleurales fueron más frecuentes en las fases intermedia/progresiva y avanzada. La mediana del score de gravedad fue de 10 (RIQ: 5-13), aumentando los valores con la progresión de la enfermedad. El acuerdo interobservador (kappa, k) para la apariencia, la distribución y el patrón predominante, así como para el score visual fueron de 0,92; 0,84; 0,70, y 0,89; respectivamente. Conclusión: Los hallazgos tomográficos en la COVID-19 varían con el curso de la infección. El score radiológico sugerido es una herramienta sencilla, reproducible y fiable para evaluar la afectación pulmonar en la neumonía COVID-19.
