New three-dimensional/four-dimensional volume rendering imaging software for detecting the abnormally invasive...

Area of Science:

• Medical imaging
• Obstetrics and Gynecology
• Diagnostic Ultrasound

Background:

• Abnormally invasive placenta (AIP) poses significant risks during pregnancy.
• Accurate preoperative diagnosis of AIP is crucial for surgical planning and patient outcomes.
• Conventional ultrasound (US) may have limitations in definitively diagnosing AIP and its depth of invasion.

Purpose of the Study:

• To evaluate the diagnostic role of three-dimensional/four-dimensional (3D/4D) volume rendering ultrasound (VRU) in abnormally invasive placenta (AIP).
• To assess the accuracy of 3D/4D VRU in determining the site and depth of placental invasion.
• To compare 3D/4D VRU findings with intraoperative results for AIP diagnosis.

Main Methods:

• Prospective observational study of 12 patients with suspected AIP.
• Utilized a Samsung WS 80A Elite US scanner with "crystal vue" and "realistic vue" 3D/4D VRU modes.
• Compared VRU diagnoses with intraoperative findings for validation.

Main Results:

• 3D/4D VRU confirmed all surgically confirmed AIP cases.
• The technique correctly diagnosed the degree of invasion in 11 out of 12 suspected AIP cases.
• Specific accuracy noted for placenta percreta (5/5), placenta increta (3/3), and placenta accreta (2/3), with one misdiagnosis of accreta degree.

Conclusions:

• 3D/4D VRU is a promising technique for the preoperative diagnosis of AIP.
• This advanced ultrasound software aids in the accurate staging of placental invasion.
• VRU enhances diagnostic confidence and surgical preparedness for AIP cases.
