摘要

目的:探讨深度学习(DL)在膀胱t2加权成像(T2DL)中与标准t2加权涡轮自旋回波(TSE)成像(T2S)相比在采集时间(TA)、图像质量和诊断置信度方面的价值。方法:我们前瞻性地招募了28例连续患者来评估膀胱癌。对每个被试进行3个平面的T2S和T2DL序列,比较两种采集方案的采集时间。图像评估由两名放射科医生独立进行,使用5点李克特量表对伪影、噪声、整体图像质量和诊断置信度进行评估,5表示最佳质量。另外,2名阅读者根据膀胱成像报告和数据系统(VI-RADS)进行T2评分。结果:与T2S相比,T2DL的轴位采集时间缩短49.4%,冠状位和矢状位采集时间缩短43.8%。与T2S相比,T2DL的伪影和噪声水平的严重程度和影响更大(在轴位和矢状位成像中,两种伪影和噪声水平均高于T2S (p均0.05)。结论:我们的研究初步证明了t2加权成像与DL重建膀胱MR在临床中的可行性。与标准T2 TSE序列相比,T2DL实现了采集时间的缩短,优越的病变可检测性和整体图像质量,具有相似的诊断置信度和T2评分。

Optimizing bladder magnetic resonance imaging: accelerating scan time and improving image quality through deep learning

Purpose

To investigate the value of deep learning (DL) in T2-weighted imaging (T2DL) of the bladder regarding acquisition time (TA), image quality, and diagnostic confidence compared to standard T2-weighted turbo-spin-echo (TSE) imaging (T2S).

Methods

We prospectively enrolled a total of 28 consecutive patients for the evaluation of bladder cancer. T2S and T2DL sequences in three planes were performed for each participant, and acquisition time was compared between the two acquisition protocols. The image evaluation was conducted independently by two radiologists using a 5-point Likert scale for artifacts, noise, overall image quality, and diagnostic confidence, with 5 indicating the best quality. Additionally, T2 scoring based on Vesical Imaging-Reporting and Data System (VI-RADS) was performed by two readers.

Results

Compared to T2S, the acquisition time of T2DL was reduced by 49.4% in the axial and by 43.8% in the coronal and sagittal orientations. The severity and impact of artifacts and noise levels were superior in T2DL versus T2S (both p < 0.05). The overall image quality in T2DL was demonstrated to be higher compared to that in T2S in axial and sagittal imaging (both p < 0.05). The diagnostic confidence and T2 scoring of both sequences in all planes did not differ (p > 0.05).

Conclusions

Our study preliminarily demonstrated the feasibility of T2-weighted imaging with DL reconstruction of bladder MR in clinical practice. T2DL achieved a reduction in acquisition time, superior lesion detectability, and overall image quality with similar diagnostic confidence and T2 score compared to the standard T2 TSE sequence.
