ACR Appropriateness Criteria® Postpartum Hemorrhage.

Postpartum hemorrhage (PPH) can be categorized as primary or early if occurring in the first 24 hours after delivery, whereas late or delayed PPH occurs between 24 hours and 6 weeks. Most of the causes of PPH can be diagnosed clinically, but imaging plays an important role in the diagnosis of many causes of PPH. Pelvic ultrasound (transabdominal and transvaginal with Doppler) is the imaging modality of choice for the initial evaluation of PPH.

ACR Appropriateness Criteria® Female Infertility.

The most common known causes of female infertility are male factor (26%), ovulatory failure (21%), and tubal damage (14%), while in 28% a couple's infertility remains unexplained. Female-specific causes of infertility include deterioration of oocyte quality with increasing maternal age; ovulatory disorders, most notably polycystic ovarian syndrome; history of salpingitis such as that caused by chlamydia infection; endometriosis; and uterine cavity abnormalities interfering with implantation causing inability to become pregnant or causing recurrent pregnancy loss. These potential causes of female infertility are discussed in this document and the appropriate imaging recommendations for each variant are provided.

Sequencing Ipilimumab Immunotherapy Before or After Chemotherapy (Nab-Paclitaxel and Bevacizumab) for the Treatment of BRAFwt (BRAF Wild-Type) Metastatic Malignant Melanoma: Results of a Study of Academic and Community Cancer Research United (ACCRU) RU261206I.

Objectives: With the introduction of novel immune therapeutics for the treatment of disseminated malignancies, we sought to evaluate whether deliberate sequencing of immunotherapy before/after conventional cytotoxic chemotherapy would have an impact on clinical outcomes in patients with previously treated metastatic melanoma. We sought to evaluate whether or not ipilimumab immunotherapy administered before or after cytotoxic chemotherapy (nab-paclitaxel+bevacizumab, AB) would impact clinical outcomes.

Methods: We conducted a randomized phase 2 clinical trial of patients with BRAF wild-type metastatic melanoma (up to 2 prior therapies) who received either: (A) AB followed by ipilimumab therapy at progression; or (B) ipilimumab followed by AB treatment at progression.

ACR Appropriateness Criteria Clinically Suspected Adnexal Mass, No Acute Symptoms.

There are approximately 9.1 pelvic surgeries performed for every histologically confirmed adnexal malignancy in the United States, compared to 2.3 surgeries per malignancy (in oncology centers) and 5.

Incidence of major hemorrhage after aggressive image-guided liver mass biopsy in the era of individualized medicine.

Purpose: To analyze a large volume of image-guided liver mass biopsies to assess for an increased incidence of major hemorrhage after aggressive liver mass sampling, and to determine if coaxial technique reduces major hemorrhage rate.

Methods: Patients who underwent image-guided liver mass biopsy over a 15-year period (December 7, 2001-September 22, 2016) were retrospectively identified. An aggressive biopsy was defined as a biopsy event in which ≥ 4 core needle passes were performed.

ACR Appropriateness Criteria Staging and Follow-Up of Ovarian Cancer.

In the management of epithelial ovarian cancers, imaging is used for cancer detection and staging, both before and after initial treatment. The decision of whether to pursue initial cytoreductive surgery for ovarian cancer depends in part on accurate staging. Contrast-enhanced CT of the abdomen and pelvis (and chest where indicated) is the current imaging modality of choice for the initial staging evaluation of ovarian cancer.

ACR Appropriateness Criteria Ovarian Cancer Screening.

There has been much interest in the identification of a successful ovarian cancer screening test, in particular, one that can detect ovarian cancer at an early stage and improve survival. We reviewed the currently available data from randomized and observational trials that examine the role of imaging for ovarian cancer screening in average-risk and high-risk women. We found insufficient evidence to recommend ovarian cancer screening, when considering the imaging modality (pelvic ultrasound) and population (average-risk postmenopausal women) for which there is the greatest available published evidence; randomized controlled trials have not demonstrated a mortality benefit in this setting.

Safety and Accuracy of Percutaneous Image-Guided Core Biopsy of the Spleen.

Objective: The purpose of this study is to assess the complication rate and diagnostic accuracy of percutaneous image-guided core needle biopsy (CNB) of the spleen at a single center over the course of 12 years.

Materials And Methods: A retrospective review of an institutionally maintained biopsy database was used to identify CNBs of the spleen performed between October 2002 and January 2015. Clinical notes were reviewed from the date of biopsy to 3 months after biopsy to ascertain whether any immediate or delayed complications had occurred.

ACR Appropriateness Criteria® Acute Pelvic Pain in the Reproductive Age Group.

Acute pelvic pain in premenopausal women frequently poses a diagnostic dilemma. These patients may exhibit nonspecific signs and symptoms such as nausea, vomiting and leukocytosis. The cause of pelvic pain includes a myriad of diagnostic possibilities such as obstetric, gynecologic, urologic, gastrointestinal, and vascular etiologies.

Hysterosalpingography After Radiofrequency Endometrial Ablation and Hysteroscopic Sterilization as a Concomitant Procedure.

Objective: To evaluate the accuracy of hysterosalpingography (HSG) in patients who underwent concomitant radiofrequency endometrial ablation and hysteroscopic sterilization.

Methods: This historical cohort study was conducted at a midwestern academic medical center. A total of 186 women (94 with combined procedure and 92 with sterilization alone) were identified as having undergone intervention between January 1, 2003, and June 30, 2011.

ACR appropriateness Criteria® infertility.

Appropriate imaging for women undergoing infertility workup depends upon the clinician's suspicion for potential causes of infertility. Transvaginal US is the preferred modality to assess the ovaries for features of polycystic ovary syndrome (PCOS), the leading cause of anovulatory infertility. For women who have a history or clinical suspicion of endometriosis, which affects at least one third of women with infertility, both MRI and pelvic US can provide valuable information.

ACR Appropriateness Criteria pelvic floor dysfunction.

Pelvic floor dysfunction is a common and potentially complex condition. Imaging can complement physical examination by revealing clinically occult abnormalities and clarifying the nature of the pelvic floor defects present. Imaging can add value in preoperative management for patients with a complex clinical presentation, and in postoperative management of patients suspected to have recurrent pelvic floor dysfunction or a surgical complication.

ACR appropriateness Criteria® second and third trimester bleeding.

Vaginal bleeding occurring in the second or third trimesters of pregnancy can variably affect perinatal outcome, depending on whether it is minor (i.e. a single, mild episode) or major (heavy bleeding or multiple episodes.

ACR Appropriateness Criteria® growth disturbances - risk of intrauterine growth restriction.

Fetal growth disturbances include fetuses at risk for intrauterine growth restriction. These fetuses may have an estimated fetal weight at less than the 10% or demonstrate a plateau of fetal growth with an estimated fetal growth greater than the 10%. Uteroplacental insufficiency may play a major role in the etiology of intrauterine growth restriction.

ACR appropriateness Criteria® first trimester bleeding.

Vaginal bleeding is not uncommon in the first trimester of pregnancy. Ultrasound is the foremost modality for evaluating normal development of the gestational sac and embryo and for discriminating the causes of bleeding. While correlation with quantitative βHCG and clinical presentation is essential, sonographic criteria permit diagnosis of failed pregnancies, ectopic pregnancy, gestational trophoblastic disease and spontaneous abortion.

ACR Appropriateness Criteria® clinically suspected adnexal mass.

Adnexal masses are a common problem clinically and imaging-wise, and transvaginal US (TVUS) is the first-line imaging modality for assessing them in the vast majority of patients. The findings of US, however, should be correlated with the history and laboratory tests, as well as any patient symptoms. Simple cysts are uniformly benign, and most warrant no further interrogation or treatment.

Uterine ultrasound findings after radiofrequency endometrial ablation: correlation with symptoms.

Objectives: To determine pelvic ultrasound characteristics in women after radiofrequency endometrial ablation (EA) and evaluate the association of those characteristics with symptoms and the need for subsequent therapeutic intervention.

Methods: This retrospective cohort study evaluated patients who underwent transvaginal pelvic ultrasound after radiofrequency EA between July 3, 2006, and November 13, 2009. The presence or absence of postablation symptoms (pelvic pain or vaginal bleeding) at the time of ultrasound defined the 2 groups.

Echogenic foci in the ovary: are they predictive of endometriosis?

Objectives: The purpose of this study was to determine whether sonographically depicted echogenic foci are more common in the ovaries of women with endometriosis when compared to the ovaries of women who do not have endometriosis.

Methods: Two radiologists blinded to the pathologic results reviewed the preoperative pelvic sonograms of consecutive women with a surgical diagnosis of endometriosis between June 2006 and October 2007. Results were compared with the preoperative sonograms of a control group of women without surgical evidence of endometriosis.
