In refractory meningiomas, the most reliable predictors of tumor uptake during 177Lu-DOTATATE PRRT are pre-treatment 68Ga-DOTATOC PET SUVmean values. Utilizing a 17-fold meninges SUVpeak segmentation method, the assessment of metabolic tumor volume on pre-therapeutic 68Ga-DOTATOC PET scans of refractory meningioma patients receiving 177Lu-DOTATATE is demonstrated to be equivalent to the routine manual segmentation method, thereby minimizing inter- and intra-observer variations. The semi-automated meningioma segmentation technique, applicable to routine practice, is also easily transferrable between PET centers.
To quantify the diagnostic contribution of contrast-enhanced MR angiography (CE-MRA) in identifying residual brain arteriovenous malformations (AVMs) after treatment.
From the electronic databases of PubMed, Web of Science, Embase, and the Cochrane Library, we gathered appropriate references, which were further analyzed for methodological quality, employing the QUADAS-2 tool. A bivariate mixed-effects model was applied to derive the pooled sensitivity and specificity, and publication bias was identified through a Deeks' funnel plot. The values of I are to be considered.
In order to identify and understand the causes of heterogeneity, testing and meta-regression analyses were applied.
Our analysis incorporated seven eligible studies, including a total of 223 participants. Compared to a benchmark, CE-MRA demonstrated sensitivity and specificity for residual brain AVM detection at 0.77 (95% CI 0.65-0.86) and 0.97 (95% CI 0.82-1.00), respectively. Pathologic response The summary ROC curve demonstrated an AUC of 0.89 (95% confidence interval 0.86-0.92). A diversity of characteristics was evident in our investigation, most notably in the specificity aspect of (I).
Seventy-four point two three percent represents the return. Subsequently, the investigation revealed no instances of publication bias.
Our research provides compelling evidence that cerebral micro-arterial angiography (CE-MRA) shows excellent diagnostic power and specificity in the long-term monitoring of treated brain arteriovenous malformations. However, owing to the constrained sample size, diverse patient populations, and numerous elements potentially impacting diagnostic accuracy, further investigation with a larger, prospective cohort is essential for confirming the results.
Pooled sensitivity and specificity of contrast-enhanced magnetic resonance angiography (CE-MRA) for the detection of residual arteriovenous malformations (AVMs) were 0.77 (95% confidence interval 0.65-0.86) and 0.97 (95% confidence interval 0.82-1.00), respectively. The four-dimensional CE-MRA technique demonstrated lower sensitivity in assessing treated AVMs in comparison to the three-dimensional CE-MRA. CE-MRA proves beneficial in the detection of residual arteriovenous malformations (AVMs), thereby minimizing the need for excessive digital subtraction angiography (DSA) in subsequent monitoring.
Contrast-enhanced MR angiography (CE-MRA) displayed pooled sensitivity and specificity values of 0.77 (95% confidence interval 0.65-0.86) and 0.97 (95% confidence interval 0.82-1.00), respectively, in identifying residual arteriovenous malformations (AVMs). In contrast to the three-dimensional CE-MRA, the four-dimensional contrast-enhanced magnetic resonance angiography (CE-MRA) displayed lower sensitivity in evaluating treated arteriovenous malformations (AVMs). CE-MRA's application in follow-up care is beneficial in pinpointing residual arteriovenous malformations (AVMs) and limiting the necessity of excessive digital subtraction angiography (DSA) procedures.
Diffusion-relaxation correlation spectrum imaging (DR-CSI) was explored for its prospective value in assessing the consistency and completeness of pituitary adenoma resection (PAR).
Prospectively, 44 patients having PAs were incorporated into the study group. The surgical assessment of tumor consistency, categorized as soft or hard, was complemented by a subsequent histological examination. A peak-based strategy was applied to segment the spectra obtained from in vivo DR-CSI. The segmented spectra were categorized into four compartments, designated as A (low ADC), B (intermediate ADC, short T2), C (intermediate ADC, long T2), and D (high ADC). Using a univariable approach, the volume fractions ([Formula see text], [Formula see text], [Formula see text], [Formula see text]), along with ADC and T2 measurements, were analyzed to determine the characteristics distinguishing hard and soft PAs. To pinpoint the determinants of EOR exceeding 95%, a logistic regression model and receiver-operating-characteristic analysis were applied.
Tumor consistency was categorized as either soft, with 28 instances, or hard, with 16 instances. Hard PAs manifested higher [Formula see text] (p=0.0001) and lower [Formula see text] (p=0.0013) values than their soft PA counterparts; however, no statistically noteworthy difference was observed in other measured parameters. A notable correlation was observed between [Formula see text] and collagen content levels (r = 0.448, p = 0.0002). A statistically significant, independent relationship was found between EOR exceeding 95% and Knosp grade (odds ratio [OR], 0.299; 95% confidence interval [CI], 0.124-0.716; p=0.0007) and [Formula see text] (odds ratio [OR], 0.834, per 1% increase; 95% confidence interval [CI], 0.731-0.951; p=0.0007). The predictive model incorporating these variables achieved an AUC of 0.934 (90.9% sensitivity and specificity), thus surpassing the performance of the Knosp grade alone (AUC 0.785, p<0.005).
