RESUMO

Background: Differences in dominance and stenosis in the complex vertebral artery (VA) network pose challenges in diagnosing and treating cerebrovascular diseases crucial for brain nutrition. This research examines these intricacies, highlighting the importance of detailed diagnosis and treatment methods. Objective: To analyze the prevalence of the dominant VA, evaluate the influence of gender and age on steno-occlusion, and explore the correlation between the dominant VA and stenosed VA segments. Methods: A retrospective study of 249 angiograms from patients with VA stenosed at King Abdullah University Hospital between August 2019 and December 2022. The patients presenting symptoms of vertigo, migraines, headaches, or transient ischemic attacks (TIA) were included, 182 cases were classified based on VA dominance and stenosis severity. The data were analyzed using IBM SPSS 27. Results: Out of the 182 participants, 64.8% were male, with an average age of 61.3 years and 35.2% were female. The prevalence of stenosis was distributed as follows: 26.4% mild, 44.0% moderate, and 29.7% severe. Statistically significant correlations were observed between hypertension, smoking, hyperlipidemia, and the degree of stenosis (p < 0.05), but not with diabetes. The prevalence of left vertebral artery (VA) dominance was found to be 41.1%. Additionally, there was no gender connection observed in the distribution of steno-occlusion (p = 0.434). There is no notable correlation between the degree of stenosis and the dominant vertebral artery (p > 0.05). Conclusion: Angiographic findings reveal the complex relationship between the dominance of the VA, patterns of stenosis, and demographic factors. Individuals with a dominant VA had a greater likelihood of developing stenosis on the opposite non-dominant side. The high occurrence of severe stenosis highlights the need for tailored diagnostic and treatment approaches. Understanding vertebral stenosis as a multifaceted interaction of demographic, lifestyle, and anatomical variables is essential for enhancing treatment strategies.

RESUMO

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.

RESUMO

Breast MRI possesses high sensitivity for detecting breast cancer among the current clinical modalities and is an indispensable imaging practice. Breast MRI comprises diffusion-weighted imaging, ultrafast, and T2 weighted and T1 weighted CE (contrast-enhanced) imaging that may be utilized for improving the characterization of the lesions. This multimodal evaluation of breast lesions enables outstanding discrimination between the malignant and benign and malignant lesions. The expanding indications of breast MRI confirm the far superiority of MRI in preoperative staging, especially in the estimation of tumour size and identifying tumour foci in the contralateral and ipsilateral breast. Recent studies depicted that experts can meritoriously utilize this tool for improving breast cancer surgery despite their existence of no significant long term outcomes. For managing the, directly and indirectly, associated screening cost, abbreviated protocols are found to be more beneficial. Further, in some of the patients who were treated with neoadjuvant chemotherapy, breast MRI is utilized for documenting response. It is therefore essential to realise that oncological screening must be easily available, cost-effective, and time-consuming. Earlier detection of this short sequence protocol leads to prior and early breast cancer disease in high risky female populations like women with dense breasts, prehistoric evidence, etc. This proper utilization of AP reduces unnecessary mastectomies. Hence, this review focused on the explorative information for strongly suggesting the benefits of AP breast MRI compared to full diagnostic protocol MRI.

RESUMO

Purpose: The absence of ionizing radiation in MRI applications does not guarantee absolute safety. Implementing of safety guidelines can ensure high-quality practice in the clinical MRI with the minimum risk. For this purpose, this cross-section quantitative study conducted in Jordan Kingdom aimed to assess current MRI safety guidelines in comparison with those of 2020 Manual on MR Safety of the American College of Radiology (ACR). Patients and Methods: A site observation study of 38 MRI units was undertaken in June 2021. A well-structured MRI safety questionnaire was the primary data collection method. Data were subjected to a descriptive statistics content analysis by the SPSS version 20. The results were analyzed to yield comprehensive discussions. Results: A total of 38 MRI facilities in participated in this study with the responding rate of 44.7%. Patient screening areas and changing rooms were available in about 29% (11/38) of the MRI facilities. Most facilities (55%, 21/38) conducted verbal screening only whereas 21% implemented both written and verbal screening for their patients and companions in zone II, which was present in a percentage of 29% in the approached facilities. Meanwhile, only 13 (43.2%) of 38 facilities used handheld magnets for physical screening, 25 (65.8%) of MRI units did not use any kind of ferromagnetic metal detection systems. Three (7.9%) participating centers had MR-safe wheelchairs, ventilators, anesthesia machines, and stretchers. Most MRI facilities participating in this study (71%) had emergency preparedness plans for alternative power outages. Despite a relatively low number of participating centers having an emergency exit or code (26.3% and 10.5%, respectively), none of them performed practice drills for such scenarios. Conclusion: Investing in new MR-safe equipment requires introducing ferromagnetic detecting systems. More research is needed to establish the degree of MRI professional's safety-related education.
