56, Yes |
1.0 T Multiplanar T 2W, T 1W two experienced reviewers, Consensus reporting |
Uterine buds: Present (78%),bilateral (61%). 100% accurate for bud cavitation. Fibrous remnants: not evaluated Ovaries: 14.5% ectopic Vagina:Lower 1/3rd vagina present in 17/56 patients Renal anomalies: 11% patients MRI sensitivity- 81.42 %, good agreement with Laparoscopy (κ - 0.55). |
Similar MRI results. Larger sample Surgical correlation+ Precise location of uterine buds, volume, not assessed. No information about fibrous remnants. |
| Yoo RE et al., 2013 (6) |
15, No |
1.5 T & 3.0 T Multiplanar T 2W, T 1W imaging two experienced gynaecological radiologists, Consensus reporting |
Uterine buds: Present bilaterally in 100% patients, cavitation in 13%, Fibrous remnants: Bands present in in 100%, midline remnant in 86% patients Ovaries: 42% ectopic Vagina: lower 1/3rd present in 93% patients Renal/vertebral anomalies: 40% patients |
Higher incidence of Mullerian remnants. Smaller sample Precise location of uterine buds, volume, not assessed |
| Kara et al., 2013 (7) |
16, No |
1.5 T Multiplanar T 2W, T 1W No 3D scanning two reviewers with specialized experience, Consensus reporting |
Uterine buds: Present (68%) Precise location cavitation, volume not assessed Fibrous remnants: not evaluated Ovaries: 12.5% ectopic Vagina: Blind ending in 100% Renal anomalies: 25% Vertebral anomalies: 12.5% |
Smaller sample. Precise location of uterine buds, cavitation, volume, was not calculated. No information about fibrous remnants. |
| Craggs et al., 2013 (8) |
66, No |
1.5 T Multiplanar T 2W, T 1W images One observer with specialized experience |
Uterine buds: Present (92%), bilateral (82%), cavitation (21%), location caudal to ovaries(100%), mean bud volume 6.4 ml Fibrous remnants: Bands(6%) Ovaries: ectopic 42% Vagina:Canal present in 66%, mean length 2 cm, dimple in 33% Renal anomalies:20% |
Larger sample size The location of buds constantly caudal to ovary. Fibrous remnants uncommon. |
| Preibsch H et al., 2014 (9) |
115, Yes |
Retrospective review of routine pre-operative MRI,n o interobserver rating |
Uterine buds: Present (90%), bilateral (75%), cavitation (33%) Fibrous remnants: not evaluated Ovaries: MRI accurate in 93% patients Renal anomalies: 27% |
Much larger sample size with surgical correlation. No information about fibrous remnants, bud volumes or precise location. |
| Boruah DK et al., 2017 (10) |
11, No |
two reviewers, consensus reporting |
Uterine buds: Presence in 81%, all bilateral, Location caudal to ovary(100%), mean bud volume 2.26 ml (right) & 1.2 ml (left), cavitation (5.6%) Fibrous remnants: Bands (77.8%), midline remnant (44.4%) Ovaries: Ectopic (9%) Vagina: Meanlength 2.6 cm Renal anomalies: 9% Vertebral: 27% |
Similar results, smaller sample. No unilateral buds detected. |

92, No |
3 T Variable MRI protocol two experienced gynaecological reviewers, consensus reporting |
Uterine buds: Present (78%), bilateral (68%), cavitation in 50% Fibrous remnants: 48% of patients with bilateral buds Ovaries: Ectopic 38% Vagina: lower 1/3rd (17%), mean length 2.4 cm Associated anomalies: 50% |
Larger sample size Similar results, although mean bud volumes are much larger. No information about fibrous remnants |
