Abstract

Ectopic pregnancy occurs when implantation of the blastocyst takes place in a site other than the endometrium of the uterine cavity. Uncommon implantation sites of ectopic pregnancy include the cervix, interstitial segment of the fallopian tube, scar from a prior cesarean delivery, uterine myometrium, ovary, and peritoneal cavity. Heterotopic and twin ectopic pregnancies are other rare manifestations. Ultrasonography (US) plays a central role in diagnosis of uncommon ectopic pregnancies. US features of an interstitial ectopic pregnancy include an echogenic interstitial line and abnormal bulging of the myometrial contour. A gestational sac that is located below the internal os of the cervix and that contains an embryo with a fetal heartbeat is indicative of a cervical ectopic pregnancy. In a cesarean scar ectopic pregnancy, the gestational sac is implanted in the anterior lower uterine segment at the site of the cesarean scar, with thinning of the myometrium seen anterior to the gestational sac. An intramural gestational sac implants in the uterine myometrium, separate from the uterine cavity and fallopian tubes. In an ovarian ectopic pregnancy, a gestational sac with a thick hyperechoic circumferential rim is located in or on the ovarian parenchyma. An intraperitoneal gestational sac is present in an abdominal ectopic pregnancy. Intra- and extrauterine gestational sacs are seen in a heterotopic pregnancy. Two adnexal heartbeats suggest a live twin ectopic pregnancy. Recognition of the specific US features will help radiologists diagnose these uncommon types of ectopic pregnancy. (©)RSNA, 2015.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 7. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 05 January 2020.
All research outputs
#4,837,286
of 25,382,440 outputs
Outputs from RadioGraphics
#1,140
of 2,829 outputs
Outputs of similar age
#56,867
of 278,955 outputs
Outputs of similar age from RadioGraphics
#14
of 43 outputs
Altmetric has tracked 25,382,440 research outputs across all sources so far. Compared to these this one has done well and is in the 79th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 2,829 research outputs from this source. They typically receive a lot more attention than average, with a mean Attention Score of 11.0. This one has gotten more attention than average, scoring higher than 58% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 278,955 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 78% of its contemporaries.
We're also able to compare this research output to 43 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 67% of its contemporaries.
