“…In our referral center, all infertile women with endometriosis underwent an appropriate pre-ART workup to precisely diagnosis and stage the endometriosis. For the DIE and OMA phenotypes, the diagnosis and staging before ART of the endometriosis was based on previously published imaging criteria using transvaginal sonography (20)(21)(22), magnetic resonance imaging (23)(24)(25)(26), or endorectal ultrasonography (27). In addition, in women with a history of previous surgery, the diagnosis was also confirmed by histologic proof of endometriosis.…”

“…Median overall time to perform fusion imaging was 32 (range, [25][26][27][28][29][30][31][32][33][34][35][36][37][38][39][40] min. Median duration of Step 1 (acquisition of 3D volumes and target identification on CT and SPECT) was 10 (range, 8-12) min; of Step 2 (coregistration and synchronization of SPECT/CT and ultrasound) was 10 (range, 7-10) min; and of Step 3 (fine tuning and SPECT/CT and ultrasound fusion imaging navigation) was 12 (range, [8][9][10][11][12][13][14][15][16][17][18][19] min.…”

“…This could be explained by the fact that fusion imaging using ultrasound is an innovative technique and its possible applications in gynecology are still being explored. Millischer et al 40 were the first to describe the role of fusion imaging in gynecology. They demonstrated in a prospective study involving 17 patients that, by combining the information from both ultrasound and MRI, the performance of these imaging modalities alone in the identification of the main anatomical sites of deep infiltrating endometriosis could be improved.…”

Objective To evaluate the feasibility of fusion of ultrasound imaging and three‐dimensional (3D) single‐photon‐emission computed tomography/computed tomography (SPECT/CT) in detecting sentinel lymph nodes in women with vulvar cancer. Methods This was a prospective pilot single‐center study. Patients with vulvar cancer who were candidates for sentinel lymph‐node biopsy were enrolled between December 2018 and February 2019. Fusion imaging virtual navigation using 3D SPECT/CT and ultrasound was performed to investigate the tumor‐draining lymph node. All clinical, imaging, surgical and histological information was collected prospectively and entered into a dedicated Excel file. Feasibility and success of fusion imaging virtual navigation and time needed to perform the three steps of fusion imaging were evaluated. Results Ten lymph‐node sites were evaluated in five consecutive women with a histological diagnosis of vulvar cancer. Fusion imaging virtual navigation was feasible and completed successfully for all (10/10) draining sites. Median overall time to perform fusion imaging was 32 (range, 25–40) min and the time decreased from the first to the last examination. Conclusions The present study demonstrated that fusion imaging virtual navigation using 3D SPECT/CT and ultrasound is feasible and able to detect sentinel lymph nodes in women with vulvar carcinoma. Fusion imaging using ultrasound for detection of sentinel lymph nodes opens up multiple diagnostic and therapeutic opportunities in gynecological oncology. Copyright © 2019 ISUOG.

“…Thus fusion imaging represents a new diagnostic method that integrates both ultrasound and MRI examinations, and was recently shown to increase the diagnostic accuracy of the single imaging method 12. In particular, this diagnostic tool has been tested in the diagnosis of deep infiltrating endometriosis13 14 and in prenatal diagnosis 15. Fusion is also recognized as a guide for both diagnosis and treatment of several cancers.…”

BackgroundFusion imaging is a new diagnostic method that integrates MRI and ultrasound. It may improve the detection and staging of locally advanced cervical cancer.ObjectiveTo evaluate the feasibility and accuracy of fusion imaging in patients with locally advanced cervical cancer.MethodsPatients with suspicion of locally advanced cervical cancer at clinical examination and/or imaging, who were candidates for neoadjuvant treatment (chemotherapy or chemoradiation) followed by surgery, were prospectively enrolled between March and November 2018. MRI, ultrasound, and fusion images were obtained before and after neoadjuvant treatment. Feasibility, success of the fusion examination, and time needed to perform fusion studies were evaluated. The rates of concordance between MRI and ultrasound before and after performing fusion, using Cohen, Spearman, and McNemar tests were calculated. The agreement between MRI and ultrasound examination, and the agreement between radiologist and gynecologist during the fusion technique in assessing local extension of disease and the presence of residual disease after neoadjuvant therapy, were also analyzed. The rates of concordance between MRI and ultrasound examination before and after performing fusion imaging, using Cohen’s kappa and Spearman’s rank correlation coefficient were calculated. A McNemar test was used to assess if there were statistical significant differences in the parameters’ agreement before and after performing fusion imaging.Results40 patients were selected and of these, 33 were analyzed. A total of 52 fusion examinations were performed: 33 (63.5%) of 52 at the time of diagnosis and 19 (36.5%) of 52 after neoadjuvant treatment. Fusion imaging was feasible in 50 (96%) of 52 studies. The median overall time of fusion execution was 13 min (range 6–30) and the time spent in performing a fusion examination decreased from the first to the last examination (20 vs 6 min). The agreement between MRI and ultrasound parameters increased after performing fusion, particularly for parametrial infiltration (74% vs 86%, p=0.014 for the right posterior parametrium; 66% vs 80%, p=0.008 for the left posterior parametrium, 70% vs 82%, p=0.014 for the right lateral parametrium).ConclusionsFusion of MRI and ultrasound is feasible in patients with locally advanced cervical cancer and may increase the diagnostic accuracy of the single imaging methods. Fusion provides multiple diagnostic opportunities in gynecological oncology.
