Exploring the relationship between cognitive performance and magnetic resonance imaging diffusion parameters in elderly individuals
DOI: 10.31744/einstein_journal/2024AO1467
Highlights ■ First study to investigate associations between cognitive performance and brain magnetic resonance imaging parameters in an older Brazilian population. ■ Uses advanced magnetic resonance imaging diffusion tensor imaging and automated analysis to quantify brain changes. ■ Validates findings through comparison with data from a large UK-based cohort. ■ Focuses on region-specific assessments, such as the superior longitudinal fasciculus and other key brain areas related to cognition. ■ Demonstrates significant correlation between 3MS and MMSE cognitive scores and diffusion […]

Uretero-fallopian fistula after gynecological surgery for endometriosis: a case report
DOI: 10.31744/einstein_journal/2025RC1294
ABSTRACT The increasing use of videolaparoscopy for the complete excision of endometriotic lesions and restoration of pelvic anatomy has helped improve long-term outcomes. However, risks remain, including rare but significant complications such as salpingoureteral fistulas. Early diagnosis using imaging methods enables adequate treatment and reduces the risk of new complications. In this report, we present a case of uretero-fallopian fistula following gynecological surgery for the resection of endometriotic lesions, with intraoperative inadvertent ureteral injury. This case report aimed to highlight […]

Chronic spontaneous non-aneurysmal aortic rupture treated with endovascular surgery
DOI: 10.31744/einstein_journal/2024RC1113
ABSTRACT Spontaneous non-aneurysmal aortic rupture is rare and is usually attributed to penetrating aortic ulcers, infections, tumor infiltrations, or inflammatory and collagen diseases. Chronic rupture is infrequent but extremely rare in non-aneurysmal aortas, which makes diagnosis difficult because the absence of an aneurysm can mislead the physician to rule out rupture. Here, we describe the case of an 85-year-old male, who was undergoing oncological investigation for weight loss, inappetence, and back pain. Computed tomography and magnetic resonance imaging performed 3 […]

Effect of transcranial direct current stimulation in the initial weeks post-stroke: a pilot randomized study
DOI: 10.31744/einstein_journal/2024AO0450
Highlights Differences ≥9 points in Fugl–Meyer Assessment scores: sham>active. Connectivity measures: active>sham. ABSTRACT Objective: This study aimed at assessing the alterations in upper limb motor impairment and connectivity between motor areas following the post-stroke delivery of cathodal transcranial direct current stimulation sessions. Methods: Modifications in the Fugl-Meyer Assessment scores, connectivity between the primary motor cortex of the unaffected and affected hemispheres, and between the primary motor and premotor cortices of the unaffected hemisphere were compared prior to and following six […]

Acute ankle injuries: association between sprain severity and ancillary findings
DOI: 10.31744/einstein_journal/2023AO0162
Highlights Participants presenting acute ankle sprains (<15 days) were divided into low-grade versus high-grade sprain, according to the presence of a complete tear in at least one component of lateral ligament complex. High-grade ankle sprains group presented increased rates of medial malleolus bone bruise, deltoid ligament tears, extensor retinaculum lesions, and articular effusion. Thecalcaneonaviculardistancewasstatisticallyshorterin patients with high-grade sprains (median, 3.0mm) when compared to those with low-grade sprains (median, 4.0mm). INTRODUCTION Ankle fractures and sprains are extremely common injuries, among the […]

Prostate imaging features on magnetic resonance imaging of young patients
DOI: 10.31744/einstein_journal/2022AO0024
ABSTRACT Objective To identify magnetic resonance imaging findings of the prostate in young adults, including symptomatic and asymptomatic patients. The aim of this study is to evaluate the main aspects of prostate imaging in young patients. Methods A total of 102 patients under 40 years of age, who underwent prostate magnetic resonance imaging between January 2016 and January 2019, were included in this study. The patients were divided into two groups: symptomatic for prostatitis (Group 1) and asymptomatic (Group 2). […]

Incidence of adhesive capsulitis of the shoulder during the beginning of the COVID-19 pandemic
DOI: 10.31744/einstein_journal/2022AE0163
ABSTRACT Objective Adhesive capsulitis is an inflammatory disease of the joint capsule, clinically manifested as pain, stiffness, and dysfunction of the shoulder. We subjectively observed an increased incidence of adhesive capsulitis, and raised the hypothesis that adhesive capsulitis was more frequent in magnetic resonance imaging examinations performed during the COVID-19 pandemic as compared with examinations prior to this period. Methods Data from medical records and magnetic resonance imaging of the shoulder presenting typical imaging findings of adhesive capsulitis, performed in […]

FAST breast magnetic resonance imaging: a new approach for breast cancer screening?
DOI: 10.31744/einstein_journal/2022AO0073
ABSTRACT Objective To develop an abbreviated breast magnetic resonance imaging protocol (FAST) and to compare it with the complete protocol (FULL) to determine its diagnostic accuracy for detecting malignant or suspicious lesions (BI-RADS 4, 5 and 6) and the time required for image interpretation using BI-RADS categorization. Methods Retrospective study with 100 consecutive women who underwent breast magnetic resonance imaging between January and February 2014. All patients were submitted to a complete breast magnetic resonance imaging protocol, which was then […]

T2-weighted imaging hypointensity in an ovarian lesion: is it a benign finding?
DOI: 10.31744/einstein_journal/2022AO6851
ABSTRACT Objective To evaluate whether the presence of a hypointense signal at T2-weighted imaging in a solid ovarian lesion on magnetic resonance imaging is a predictor of stability and benignity. Methods This is a single center study, prospectively read with retrospective acquired data. The database was searched for patients who underwent magnetic resonance imaging between January 2008 and October 2019 and whose reports mentioned solid ovarian lesions with low signal on T2-weighted imaging. A total of 47 nodules were included. […]
