Efficacy of saline tract sealing after CT-Guided lung biopsy: a systematic review and meta-analysis

Jun 20, 2026

The authors aimed to evaluate the efficacy of saline tract sealing in reducing the incidence of pneumothorax and the need for chest tube placement following CT-guided lung biopsy. Their systematic review and meta-analysis of seven studies, involving 1,455 patients, found that saline tract instillation significantly decreased both pneumothorax rates and chest tube placements compared to usual care. These findings suggest that saline tract sealing is an effective technique to enhance patient outcomes in lung biopsy procedures.

Automated computed tomography (CT) perfusion in the assessment of the ischaemic core in wake-up strokes: is it reliable?

Jun 19, 2026

The authors aimed to evaluate the reliability of computed tomography perfusion (CTP) in assessing the ischaemic core in patients with wake-up strokes. Their findings indicate that CTP alone is not a reliable method, as it underestimated the ischaemic core in 38% of cases compared to non-contrast CT, suggesting that both imaging techniques should be used together to accurately determine thrombectomy eligibility in this patient population.

Effect of myocardial bridging on the fat attenuation index of proximal coronary arteries: a dual-centre study in a plaque-free population

Jun 19, 2026

This study aimed to investigate the relationship between myocardial bridging of the left anterior descending artery and the fat attenuation index (FAI) of proximal coronary arteries in a plaque-free population. The findings revealed that deeper myocardial bridges are associated with significantly higher FAI values, with MB thickness being the key anatomical factor linked to this elevation, while MB length showed no significant correlation.

The value of microvascular flow imaging and color Doppler flow imaging in the differential diagnosis of benign and malignant endometrial lesions

Jun 18, 2026

The authors aimed to evaluate the effectiveness of microvascular flow (MV-Flow) imaging and its quantitative parameter, the vascular index (VI^MV), in differentiating between benign and malignant endometrial lesions compared to color Doppler flow imaging (CDFI). The study found that MV-Flow provided superior blood flow detection rates and clearer visualization of microvessels, with VI^MV demonstrating high diagnostic sensitivity and specificity, thus highlighting its potential as a valuable tool in the differential diagnosis of endometrial lesions.

Cervical subcutaneous fat index and lordosis in intervertebral disc degeneration: is there a link?

Jun 17, 2026

This study aimed to investigate the relationship between cervical intervertebral disc degeneration (IVDD), cervical lordosis angle (CL), and posterior subcutaneous fat index (SFI) in adults with neck pain. The findings indicated no significant associations between SFI, CL, and IVDD, although a notable degeneration was observed at the C6-7 level in the normal lordosis group. The authors conclude that cervical disc degeneration is multifactorial and call for larger prospective studies to further explore these relationships.

Delayed 18F-FDG PET for the evaluation of suspected recurrent disease in brain metastases treated with radiation

Jun 15, 2026

The authors aimed to evaluate the diagnostic utility of dual-timepoint 18F-FDG PET imaging in distinguishing progressive disease (PD) from radiation necrosis (RN) in patients with brain metastases showing suspicious MRI findings. Their findings indicate that the delayed T/B SUVmax ratios from PET imaging significantly differentiate PD from RN, potentially reducing false-positive diagnoses in equivocal MRI cases. However, they emphasize the need for prospective validation and standardized protocols to confirm these results.

Hypertension and myocardial fibrosis: A systematic review and meta-analysis

Jun 15, 2026

This meta-analysis investigates the relationship between hypertension (HTN) and myocardial fibrosis (MF), aiming to quantify the association using imaging and histological data. The findings indicate that HTN is significantly linked to increased indicators of MF, and certain antihypertensive medications, such as losartan and ramipril, may help reduce MF, while others do not show significant effects. The study highlights the importance of identifying MF in hypertensive patients and suggests tailored medication strategies to mitigate its impact.

ADC histogram analysis for differentiating high-grade and low-grade meningiomas: a systematic review and meta-analysis

Jun 15, 2026

The authors aimed to evaluate the effectiveness of ADC histogram analysis in preoperatively grading meningiomas, as accurate grading is crucial for treatment and prognosis. Their systematic review and meta-analysis of six studies involving 533 patients found that ADC histogram analysis demonstrated a pooled sensitivity of 71% and specificity of 72%, indicating its potential to enhance surgical decision-making and personalized patient management. They suggest that further research is needed for standardization and multicenter validation of this approach.

Deep learning for visceral pleural invasion in non-small cell lung cancer

Jun 15, 2026

The authors aimed to evaluate and compare the diagnostic performance of deep learning models and a conventional clinical-radiological feature model for predicting visceral pleural invasion (VPI) in non-small cell lung cancer using preoperative CT scans. While the clinical model demonstrated higher specificity, it had low sensitivity, whereas the best-performing deep learning model showed improved sensitivity but lower positive predictive value. Overall, neither approach achieved optimal clinical utility, indicating the need for further advancements in noninvasive VPI prediction methods.

Preoperative contrast enhanced mammography evaluation of breast ductal carcinoma in situ and comparative analysis with pathological grading

Jun 13, 2026

The authors aimed to evaluate the effectiveness of contrast-enhanced mammography (CEM) in diagnosing breast ductal carcinoma in situ (DCIS) and to explore the relationship between CEM findings and the pathological nuclear grades of DCIS. The study found that CEM demonstrated significantly higher sensitivity compared to low-energy imaging and revealed distinct manifestations of DCIS based on nuclear grade, with high-grade lesions showing more calcifications and larger sizes. Overall, CEM proved to be a superior diagnostic tool for DCIS, providing valuable insights into the characteristics of different nuclear grades.
