Background: Adnexal Torsion
(AT), serious emergency of gynecology, frequently shows among nonspecific signs
prominent to late analysis.
Aim: To compare the test accuracy of Ultrasound,
Computed Tomography (CT) and Magnetic Resonance Imaging (MRI) for diagnosis of
Methodology: We observed google scholar as well as
Radiographics key till Dec 2019. Assortment standards studies report upon Imaging
Modality accuracy (index test) within paediatric and adult females alleged of
adnexal torsion matched by clinical analysis or usual clinical or radiological
follow up duration till symptoms firmness (reference standard).
Results: We mark off
3836 references, comprised 18 Studies (1654 females, 665-cases), as well as comprised
15 into meta analyses, ultrasound pooled-sensitivity (n =12, 1187 females) was
0.79 (95% CI= 0.63 to 0.92) as well as specificity was 0.76 (95% CI= 0.54 to 0.93),
by means of positive as well as negative probability fractions 4.35 (95% CI=
2.03 to 9.32) and 0.29 (95% CI= 0.13 to 0.66), correspondingly. By Doppler
Ultrasound (n=7, 845 females) produced alike and specificity (0.88, 95% CI=
0.72 to 1.00) and sensitivity (0.80, 95% CI= 0.67 to 0.93). For magnetic
resonance imaging (n=3, 99 females), pooled-sensitivity was 0.81 (95% CI=0.63
to 0.91) as well as specificity was 0.91 (95% CI= 0.80 to 0.96). Meta-analysis
for Computed Tomography was impossible by 2 case control-studies as well as one
cohort-study (n=3, 232 females). Its range of sensitivity was 0.74 to 0.95 as
well as specificity 0.80 to 0.90.
Conclusions: As a first line analytic examination for
alleged AT, ultrasound has good performance. Increment in quantity of AT cases
needs precise, rapid, as well as correct analytic extent. It has been utmost
popular method as allied with further Imaging Modalities. MRI might compromise
better specificity for investigating intricate morphology of ovary, nonetheless
further proof is wanted. Beside with medical doubt as well as approximations.
This study will offer sufficient appreciated evidence to understand sonographic
markers impact during OT analysis precisely.
