Introduction 3D scanning can enhance the ability of a clinician to make an accurate diagnosis. The aim of this study was to evaluate the usage of 3D scanning in making a correct diagnosis of uterine anomalies and location of intrauterine contraception (IUC).

Methods It was a retrospective analysis of patient’s notes that had 2D and 3D ultrasound done in Sexual and Reproductive healthcare clinic over a period of 6 months. All patients who had ultrasound done in relation to coil were included. The exclusion criteria were when ultrasound was done in terms of pelvic pain or bleeding and patient was not using IUC.

Results 90 patients were included in the analysis and all of them had both; 2D and 3D ultrasound. 57% of patients attended clinic with lost threads. 13% had bleeding problems and 8% had unsuccessful removal/insertion previously.

On ultrasound examination, 88% had coil placed at fundal location and 7% had low lying coil. 5% of patients had myometrial penetration of coil. 38% of patients were reassured about coil location and in 35% of cases coil was either removed or replaced. Gynaecology referral was done in 12%. 1 patient was diagnosed with sub-septate uterus.

Discussion This study has shown that 3D scanning enhances the image quality by facilitating in the accurate location of coil especially in cases of myometrial penetration. It also helped in diagnosis of sub-septate uterus, which is not easily plausible with 2D scanning.
