Comparison of 3 Tesla MRI to 7 Tesla MRI for Evaluation of Prostate Suspicion Lesions
A comparison of 3 Tesla MRI to 7 Tesla MRI for Evaluation of Prostate Suspicious Lesions.
Assess the added diagnostic value of ultra-high-field (7T) MRI over the current clinical standard (3T MRI) in detecting and characterizing suspicious prostate lesions. Evaluate whether dynamic deuterated glucose-enhanced imaging at 7T can offer improved contrast without the use of gadolinium-based agents.

실험적: 3 Tesla (3T) versus 7 Tesla (7T) MRI in the assessment of suspicious prostate lesions
Each participant serves as their own control, undergoing both 3T and 7T MRI scans.
|
Imaging protocols will include multiparametric sequences at both field strengths, with the addition of high-resolution anatomical and optional dynamic glucose-enhanced imaging at 7T.

측정값 설명 |
기간 |
|---|---|---|
|
ROC analysis of diagnostic performance: 3T versus 7T MRI
기간: Assessed at the time of MRI acquisition during the study imaging visit.
|
ROC analysis (Receiver Operating Characteristic analysis) - A statistical method used to evaluate and compare diagnostic accuracy.
It examines how well a test distinguishes between diseased and non-diseased cases across different thresholds.
|
Assessed at the time of MRI acquisition during the study imaging visit.
|
|
Sensitivity and Specificity of diagnostic performance: 3T versus 7T MRI
기간: Assessed at the time of MRI acquisition during the study imaging visit.
|
Sensitivity - The ability of the MRI to correctly identify patients who truly have disease (true positive rate). High sensitivity means fewer missed cases. Specificity - The ability of the MRI to correctly identify patients who do not have disease (true negative rate). High specificity means fewer false alarms or false positives. |
Assessed at the time of MRI acquisition during the study imaging visit.
|
|
Lesion conspicuity of diagnostic performance: 3T versus 7T MRI
기간: Assessed at the time of MRI acquisition during the study imaging visit.
|
How clearly and visibly an abnormal lesion can be seen on MRI images compared with surrounding tissue.
Higher conspicuity generally makes lesions easier to detect and characterize.
|
Assessed at the time of MRI acquisition during the study imaging visit.
|
|
PI-RADS classification - The Prostate Imaging Reporting and Data System: 3T versus 7T MRI
기간: Assessed at the time of MRI acquisition during the study imaging visit.
|
a standardized scoring system used in prostate MRI to estimate the likelihood of clinically significant prostate cancer.
Scores range from 1 (very low likelihood) to 5 (very high likelihood).
|
Assessed at the time of MRI acquisition during the study imaging visit.
|
|
Quantitative imaging metrics of diagnostic performance: 3T versus 7T MRI
기간: Assessed at the time of MRI acquisition during the study imaging visit.
|
Numerical measurements derived from MRI images, such as lesion size, signal intensity, contrast ratios, diffusion values (e.g., ADC), or texture features, used to objectively compare imaging performance.
|
Assessed at the time of MRI acquisition during the study imaging visit.
