“…From our standpoint, SMI appears to be an extremely robust and reliable technique in the setting of neonatal ultrasound. Since initial reports in March 2016 [14], SMI has been mainly used in oncologic conditions (especially breast lesions) [22–26], infectious diseases [16, 27, 28], gastrointestinal disorders [29–32], obstetric ultrasound [33, 34], musculoskeletal [35], vascular [36], and endocrine disorders [14]. In paediatric imaging, SMI has been used to detect direction of urinary flow in patients with vesico-urethral reflux without the use of contrast [16] and to demonstrate differences in vascular flow grades between normal and undescended testes, which were invisible by Power Doppler [17, 18].…”

ObjectivesTo evaluate the feasibility and reproducibility of superb microvascular imaging (SMI) of the neonatal brain and to describe normal imaging features.MethodsWe performed transcranial ultrasound with SMI in 19 healthy term-born neonates. SMI was done according to a structured examination protocol, using two linear 18 MHz and 14 MHz transducers. Superficial and deep scans were acquired in the coronal and sagittal planes, using the left and right superior frontal gyri as anatomical landmarks. All SMI views were imaged by monochrome and colour SMI and evaluated with respect to visibility of extrastriatal (i.e. cortical and medullary) and striatal microvessels.ResultsWe have described normal morphologic features of intraparenchymal brain microvasculature as “short parallel” cortical vessels, “smoothly curved” medullary vessels, and deep striatal vessels. In general, SMI performance was better on coronal views than on sagittal views. On superficial coronal scans, cortical microvessels were identifiable in 90–100%, medullary microvessels in 95–100%. On deep scans, cortical and medullary microvessels were visible in all cases, while striatal microvessels were identifiable in 71% of cases.ConclusionsCerebral SMI ultrasound is feasible and well-reproducible and provides a novel non-invasive imaging tool for the assessment of intraparenchymal brain microvasculature (extrastriatal and striatal microvessels) in neonates without the use of contrast.Key Points• Superb microvascular imaging (SMI) of the neonatal brain is feasible and reproducible. • SMI depicts extrastriatal and striatal microvessels. • SMI detects two types of extrastriatal microvessels: cortical and medullary.Electronic supplementary materialThe online version of this article (10.1007/s00330-018-5743-1) contains supplementary material, which is available to authorized users.

“…They are usually associated with rheumatologic diseases. In one of them, the authors found significantly higher total SMI scores patients with rheumatic diseases and these scores significantly correlated with the levels of serum C‐reactive protein and matrix metalloproteinase‐3 . In another study with rheumatoid arthritis (RA), they demonstrated that SMI was more sensitive than power Doppler imaging for detecting synovial vessel signals of the hand joint in patients with RA in clinical remission .…”

Background: Cicatricial alopecia (CA) is a group of disorder characterized by permanent destruction of the hair follicle. Shear wave elastography (SWE) and superb microvascular imaging (SMI) are noninvasive ultrasonic techniques which evaluate thickness, stiffness, and vascular index of tissues.Objectives: This study explored the ranges of cicatricial alopecia area and normal scalp with a combined modality of SMI and SWE and investigated the feasibility of their use in assessing these diseases.Methods: Seventeen patients diagnosed with CA and twenty healthy controls were included in the study. SWE and SMI were performed with an Aplio 500 ultrasound system. Results:The mean age of patient group was 37.00 ± 13.16, and the mean age of the healthy controls were 36.00 ± 11.79. SWE results as m/s in cicatricial plaques (x = 5191) were higher than non-alopecic scalp areas (x = 4460) in patient group (t (16) = 2260; P = 0.038 < 0.05). SMI values in patient group (cicatricial plaques) (x = 1200) were significantly higher than control group SMI values (x = 0.005) (t (35) = 3.075; P = 0.012 < 0.05). Conclusions:To the best of our knowledge, this is the first study to evaluate SWE and SMI scores in cicatricial alopecia. We found higher stiffness and vascularity in patient group. We conclude that SWE and SMI can show fibrosis and inflammation like previous studies. Especially, SWE as m/s is more sensitive than as kPa for cicatricial alopecia.

This article reviews the clinical applications of Superb Microvascular Imaging (SMI; Canon Medical Systems, Otawara, Japan) in the liver, breast, thyroid, skeletal muscle, and carotid plaques. Diseases that are closely associated with angiogenesis can be diagnosed by SMI in a relatively early phase, and using SMI can prevent adverse reactions associated with the contrast agents used in contrast‐enhanced ultrasound. Super Microvascular Imaging also shows particular value in grading disease activities and monitoring therapeutic responses. Although SMI has some limitations, such as a lack of clinical standards, it can add information to conventional ultrasound examinations and may become a noninvasive alternative to invasive diagnostic procedures for many clinical conditions.
