UltraSight is highlighting a study showing that its point-of-care ultrasound (POCUS) AI software can help novice users interpret diagnostic cardiac images.
Researchers led by Roberto Lang, MD, of the University of Chicago, assessed the quality of echocardiographic exams performed by inexperienced users guided by Ultrasight’s software and evaluated their suitability for diagnostic interpretation of basic cardiac pathology, as well as quantitative analysis of cardiac chamber and function.
“After minimal training with the real-time guidance software, novice users can acquire images of diagnostic quality approaching that of expert sonographers in most patients,” Lang and colleagues noted, in a study published November 13 in Circulation: Cardiovascular Imaging.
In the study, the software was embedded into a handheld POCUS device (Lumify, Philips). Six nurses and three medical residents who underwent minimal training scanned 240 patients (63% with cardiac pathology) in 10 standard views. All patients were also scanned by expert sonographers using the same device without AI guidance.
The analysis showed that images obtained by novices and sonographers yielded concordant diagnostic interpretation in 83% to 96% studies. In addition, quantitative analysis was feasible in 83% of images acquired by novices and resulted in high correlations (r≥0.74) and small biases, compared with those obtained by sonographers.
The published results validate the efficacy of the technology and open up new possibilities for improved cardiovascular care and diagnostics, UltraSight said, in a news release.

![Examples of ultrasound findings and techniques. (A) Images in a 39-year-old male patient with a mass in the left thigh. The mass is heterogeneous on the B-mode US image (compared with the patient in D) and showed increased microvascularity (superb microvascular imaging [SMI]) and shear-wave elastography (SWE) values. Undifferentiated pleomorphic sarcoma was diagnosed at biopsy (with pleomorphic rhabdomyosarcoma in surgical specimen). (B) Images in an 18-year-old male patient with a mass in the left leg. The mass is hypoechoic on the B-mode image, with no other findings suggestive of malignancy. The lesion is in contact with the cortex of the tibia, which is slightly irregular. CT revealed a doubtful anteromedial tibial erosion. The microvascular study demonstrated high vascularization, suggestive of malignancy. Periosteal Ewing sarcoma was diagnosed with both histologic and immunohistochemical confirmation. (C) Images in a 69-year-old female patient with a lump growing on the outside of the left leg. Multiple SWE examinations were performed (please note the high values obtained in the measurements, whereas the color map highlights the stiffness relative to adjacent tissues). SMI showed areas of increased vascularization to target for sampling. Undifferentiated spindle cell sarcoma was diagnosed at biopsy, with residual leiomyosarcoma in the surgical specimen after neoadjuvant therapy. (D) Images in a 56-year-old female patient with a mass in the right thigh. The mass is heterogeneous at both B-mode ultrasound (similar to patient A) and MRI (coronal T2-weighted spectral attenuated inversion recovery [SPAIR]; T1-weighted pre-contrast and postcontrast imaging), which even shows uptake after the administration of paramagnetic contrast material, which is traditionally suggestive of malignancy. Low values at SMI and elastography are suggestive of benignity. Spindle cell lipoma was diagnosed at biopsy, with atypical spindle cell lipomatous tumor in the surgical specimen.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/08/images-radiol250278fig2.APCFLSvX6p.jpg?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
