MRI-ultrasound AI model beats radiologists on specificity; Toumai robot matches da Vinci in radical prostatectomy

  MRUSuNet AI combining MRI and ultrasound shows higher specificity than radiologists, 0.88 versus 0.78, in prostatectomy cohort
  An AI model that combines MRI and transrectal ultrasound images, developed in two MRI-ultrasound fusion biopsy cohorts totaling 3,000 patients, was validated in an independent radical prostatectomy cohort of 110 patients, according to a study published online Oct. 20 in BJU International. The model showed higher specificity than radiologist MRI interpretation, 0.88 versus 0.78 (P = .004), with no observed difference in sensitivity (0.79; P = 1.000). The authors said the findings show the potential of combining MRI and ultrasound in a multimodal model.

  Toumai and da Vinci robots give comparable short-term radical prostatectomy outcomes in 200-patient prospective study
  A single-center, prospective, nonrandomized study published Oct. 23 in the Journal of Robotic Surgery compared robotic radical prostatectomy on the Toumai platform with the da Vinci platform in 200 patients, 100 on each. Operative time (215.0 versus 200.3 minutes, P = .001) and console time (193.6 versus 178.0 minutes, P < .001) were longer with Toumai, while overall complications, 18% versus 10% (P = .103), and positive surgical margins, 19% versus 17% (P = .713), did not differ significantly. The authors said the platforms showed comparable short-term oncological, functional and complication outcomes.
