“…The difference of ADC among 3 DWIs may be mainly caused by the differences of susceptibility artifacts appeared in each DWI. Susceptibility artifact in SS-EPI DWI and RESOLVE DWI was more severe than that in TGSE-BLADE DWI, which suggests that susceptibility artifacts affected calculation of ADC largely in SS-EPI DWI and RESOLVE DWI 24 . However, the ICC of ADC values among the three DWIs indicates an almost perfect agreement.…”

“…There was less difference in distortion between TGSE-BLADE DWI and the other DWI sequences with increasing distance from air–bone interfaces (e.g., occipital lobe and parietal lobe). Most previous studies have performed qualitative evaluation of distortion 20 , 23 , 24 . In the present study, however, we demonstrated quantitatively that distortion was reduced in intracranial regions.…”

“…Several studies have used TGSE-BLADE DWI to reduce geometric distortion and susceptibility artifact in regions where strong magnetic susceptibility presents 20 , 24 – 26 . However, it remains unknown whether TGSE-BLADE DWI can reduce clip-induced artifact and improve image quality in patients who have undergone cerebral aneurysm clipping.…”

Diffusion-weighted magnetic resonance imaging is prone to have susceptibility artifacts in an inhomogeneous magnetic field. We compared distortion and artifacts among three diffusion acquisition techniques (single-shot echo-planar imaging [SS-EPI DWI], readout-segmented EPI [RESOLVE DWI], and 2D turbo gradient- and spin-echo diffusion-weighted imaging with non-Cartesian BLADE trajectory [TGSE-BLADE DWI]) in healthy volunteers and in patients with a cerebral aneurysm clip. Seventeen healthy volunteers and 20 patients who had undergone surgical cerebral aneurysm clipping were prospectively enrolled. SS-EPI DWI, RESOLVE DWI, and TGSE-BLADE DWI of the brain were performed using 3 T scanners. Distortion was the least in TGSE-BLADE DWI, and lower in RESOLVE DWI than SS-EPI DWI near air–bone interfaces in healthy volunteers (P < 0.001). Length of clip-induced artifact and distortion near the metal clip were the least in TGSE-BLADE DWI, and lower in RESOLVE DWI than SS-EPI DWI (P < 0.01). Image quality scores for geometric distortion, susceptibility artifacts, and overall image quality in both healthy volunteers and patients were the best in TGSE-BLADE DWI, and better in RESOLVE DWI than SS-EPI DWI (P < 0.001). Among the three DWI sequences, image quality was the best in TGSE-BLADE DWI in terms of distortion and artifacts, in both healthy volunteers and patients with an aneurysm clip.

“…Recently, TGSE BLADE DWI was shown to significantly reduce distortion, blurring, and magnetic-sensitive artifacts (10). This technique has been used to visualize orbital tumors, cerebellopontine angle tumors, and sinonasal lesions on 3T magnetic resonance images (MRI) (11–13). Recently, it has been confirmed that TGSE BLADE DWI possesses superior image quality in cholesteatoma imaging and may have a unique role in identifying particularly small cholesteatomas (14).…”

ObjectiveTo evaluate the diagnostic accuracy of 2D BLADE turbo gradient- and spin-echo diffusion weighted imaging (TGSE BLADE DWI) for primary middle ear cholesteatoma diagnosis, using qualitative and quantitative methods.Study DesignRetrospective case series.SettingUniversity hospital.PatientsParticipants included those with suspected primary middle ear cholesteatoma after assessment by clinical otorhinolaryngologists combined with magnetic resonance imaging (MRI) examination. Finally, of the 85 ears from 65 patients enrolled in the study, 73 had cholesteatoma, and 12 had otitis media.InterventionTwo radiologists independently assessed images and measured apparent diffusion coefficient (ADC) values. Sensitivity, specificity and accuracy were evaluated. Kappa (k) statistics, the intraclass correlation coefficient (ICC), the Kolmogorov–Smirnov normality test, the independent t test, and receiver operating characteristic (ROC) analysis were used for statistical analysis. Pair-wise comparison of the area under the ROC curve (AUC) was also performed using the Delong test.Main Outcome MeasuresImaging and histopathologic findings.ResultsThe mean ADC value of cholesteatoma group (mean, 0.923 ± 0.246 × 10–3 mm2/s) was significantly lower than that of noncholesteatoma group (mean, 1.744 ± 0.205 × 10–3 mm2/s; p < 0.001). In ≤3 mm cholesteatoma group, the AUC of qualitative DWI was 0.846; the sensitivity, specificity, and accuracy for diagnosing cholesteatoma were 69.23%, 100%, and 84%, respectively; while the AUC of quantitative diagnosis was significantly increased to 1.0 (p = 0.0209); and based on the optimal threshold of ADC, ≤1.352 × 10–3 mm2/s, the sensitivity, specificity and accuracy improved to 100%. For >3 mm cholesteatoma group, there were no significant differences in diagnostic performance. Excellent interobserver agreement and ICC for the qualitative and quantitative evaluations (k = 0.90 and ICC = 0.80, respectively) was noted between reviewers.ConclusionTGSE BLADE DWI is useful for the detection of primary middle ear cholesteatomas, especially ≤3 mm lesions.
