“…Quantitative SMI can be obtained using the vascular index (VI) of the nodule, which represents the ratio between the pixels of the Doppler signal and those of the whole nodule. Previous studies have utilized the color mode when conducting quantitative analysis ( 21 , 22 ). Hence, both qualitative and quantitative SMI were obtained in color mode in our study.…”

Background: To compare qualitative and quantitative superb microvascular imaging (SMI) and determine the value of SMI in the diagnosis of thyroid nodules (TNs) ≤10 mm based on the Chinese Thyroid Imaging Reporting and Data System 4 (C-TIRADS 4). Methods: From October 2020 to June 2022, 106 patients with 109 C-TIRADS 4 (C-TR4) TNs (81 malignant, 28 benign) at the Peking Union Medical College Hospital were included. Qualitative SMI reflected the vascular pattern of the TNs and quantitative SMI was recorded by the vascular index (VI) of the nodules. Results: The VI was significantly higher in malignant nodules versus benign nodules both in the longitudinal (19.9±11.4 vs. 13.8±10.6, P=0.01) and transverse (20.2±12.1 vs. 11.3±8.7, P=0.001) sections. The area under the curve (AUC) of qualitative and quantitative SMI did not show a statistical difference in the longitudinal {0.657 [95% confidence interval (CI): 0.560-0.745] vs. 0.646 (95% CI: 0.549-0.735), P=0.79} and transverse [0.696 (95% CI: 0.600-0.780) vs. 0.725 (95% CI: 0.632-0.806), P=0.51] sections. Next, we combined qualitative and quantitative SMI to upgrade and downgrade the C-TIRADS classification. If a C-TR4B nodule had VIsum >12.2 or intra-nodular vascularity, the original C-TIRADS was upgraded to C-TR4C. If a C-TR4C or C-TR4B nodule manifested VIsum ≤12.2 and no intra-nodular vascularity, the original C-TIRADS was downgraded to C-TR4A. As a result, 18 C-TR4C nodules were downgraded to C-TR4A and 14 C-TR4B nodules were upgraded to C-TR4C. The new model of SMI + C-TIRADS showed high sensitivity (93.8%) and accuracy (79.8%). Conclusions: There is no statistical difference between qualitative and quantitative SMI in the diagnosis of C-TR4 TNs. The combination of qualitative and quantitative SMI may have the potential to manage diagnosis of C-TR4 nodules.

“…In contrast, CDFI and PDI showed only sparse vessels local distributed in the local of nodule (Figure 4). Ahn HS et al 46–48 proposed that SMI can visuliaze the appearance and distribution of microvessels clearly, in addition, papillary thyroid carcinoma showed peri‐nodular vascularization and microvascularization of internal small branches in SMI mode, providing a more reliable basis for the accurate diagnosis of thyroid TI‐RADS four types of nodules. However, Jiang et al 49 retorted that, though SMI can better visualize microvessels, it is still unconvincing to judge the nature of nodule based on the number and distribution of microvessels alone, as hypovascularity may be one of the features shared by benign and malignant nodules.…”

Superb microvascular imaging (SMI) is among the latest doppler ultrasound methods. It uses an advanced clutter filter to eliminate artifacts caused by breathing, movement and retains the low‐speed blood signals in microvessels. The great advantage of SMI is that it can intuitively detect very slow blood signals in microvessels, providing clinicians with more significant information about flow distribution in the target area. Therefore, it is speculated that SMI has important application value. The purpose of this article is to outline the application of SMI in different parts of the body.

“…In light of the results of our study, drawing lesion contours manually does not contribute to any additional data about the nature of the lesion. Thus, a more easy and practical measurement method may be more suitable for SMI examination (23).…”
