Abdom Radiol (NY) 2024; 49:875-887. [PMID: 38189937 DOI: 10.1007/s00261-023-04149-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2023] [Revised: 11/28/2023] [Accepted: 11/29/2023] [Indexed: 01/09/2024]
Abstract
PURPOSE To determine whether multiparametric magnetic resonance imaging (MRI) radiomics-based machine learning methods can improve preoperative local staging in patients with endometrial cancer (EC). METHODS Data of patients with histologically confirmed EC who underwent preoperative MRI were retrospectively analyzed and divided into a training or test set. Radiomic features extracted from multiparametric MR images were used to train and test the prediction of deep myometrial invasion (DMI) and cervical stromal invasion (CSI). Two radiologists assessed the presence of DMI and CSI on conventional MR images. A combined model incorporating a radiomic signature and conventional MR images was constructed and presented as a nomogram. Performance of the predictive models was assessed using the area under curve (AUC) in the receiver operating curve analysis and pairwise comparison using DeLong's test with Bonferroni correction. RESULTS This study included 198 women (training set = 138, test set = 60). Conventional MRI achieved AUCs of 0.837 and 0.799 for detecting DMI and 0.825 and 0.858 for detecting CSI in the training and test sets, respectively. The nomogram achieved AUCs of 0.928 and 0.869 for detecting DMI and 0.913 and 0.937 for detecting CSI in the training and test sets, respectively. The ability of the nomogram to detect DMI and CSI in the two sets was superior to that of conventional MRI (adjusted p < 0.05), except for the ability to detect CSI in the test set (adjusted p > 0.05). CONCLUSION A nomogram incorporating radiomics signature into conventional MRI improved the efficacy of preoperative local staging of EC.

Abstract
MR imaging is the modality of choice for the pre-treatment evaluation of patients with gynecologic malignancies, given its excellent soft tissue contrast and multi-planar capability. However, it is not without pitfalls. Challenges can be encountered in the assessment of the infiltration of myometrium, vagina, cervical stroma, and parametria, which are crucial prognostic factors for endometrial and cervical cancers. Other challenges can be encountered in the distinction between solid and non-solid tissue and in the identification of peritoneal carcinomatosis for the sonographically indeterminate adnexal mass.

Abstract
OBJECTIVE To compare the diagnostic accuracies of ultrasound and magnetic resonance imaging (MRI) for deep (≥50%) myometrial invasion (DMI) and cervical stromal invasion (CSI) in women with endometrial cancer. METHODS This was a prospective study at a gynecology clinic for women with postmenopausal bleeding. Between October 2015-October 2018, consecutive women with suspected endometrial cancer based on ultrasound subjective pattern recognition were simultaneously assessed for DMI and CSI on ultrasound. Subsequently, they also underwent preoperative MRI. We compared the diagnostic accuracies of ultrasound and MRI in predicting DMI and CSI with the final histology as the gold standard. RESULTS We included 51 women. The prevalence of DMI and CSI were 22/51 (43%) and 7/51 (14%), respectively. The majority of malignancies were of endometrioid histological subtype (38/51, 75%) and FIGO stage 1 or 2 (40/51, 78%). Ultrasound diagnosed more cases of DMI compared to MRI (19/22 vs. 17/22), however, the difference was not statistically significant. The sensitivities and specificities of ultrasound and MRI for DMI were 86% vs. 77% and 66% vs. 76%, respectively. For CSI, ultrasound and MRI correctly diagnosed the same number of cases (5/7, 71%); their respective false-positive rates were low, 0/44 (0%) and 1/44 (2%). Ultrasound and MRI had a moderate agreement for DMI (ƙ=0.49; 95% confidence interval [CI]=0.26-0.73), whereas the agreement for CSI was substantial (ƙ=0.69; 95% CI=0.36-1.00). CONCLUSION Endometrial cancer can be simultaneously diagnosed and staged at women's initial ultrasound assessment. The accuracies of ultrasound for DMI and CSI are comparable to MRI.

Qualitative and quantitative comparison of image quality between single-shot echo-planar and interleaved multi-shot echo-planar diffusion-weighted imaging in female pelvis. Eur Radiol 2019; 30:1876-1884. [PMID: 31822971 PMCID: PMC7062860 DOI: 10.1007/s00330-019-06491-3] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Revised: 08/20/2019] [Accepted: 10/02/2019] [Indexed: 12/20/2022]
Abstract
OBJECTIVES To qualitatively and quantitatively compare the image quality between single-shot echo-planar (SS-EPI) and multi-shot echo-planar (IMS-EPI) diffusion-weighted imaging (DWI) in female pelvis METHODS: This was a prospective study involving 80 females who underwent 3.0T pelvic magnetic resonance imaging (MRI). SS-EPI and IMS-EPI DWI were acquired with 3 b values (0, 400, 800 s/mm2). Two independent reviewers assessed the overall image quality, artifacts, sharpness, and lesion conspicuity based on a 5-point Likert scale. Regions of interest (ROI) were placed on the endometrium and the gluteus muscles to quantify the signal intensities and apparent diffusion coefficient (ADC). Signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), and geometric distortion were quantified on both sequences. Inter-rater agreement was assessed using κ statistics and Kendall test. Qualitative scores were compared using Wilcoxon signed-rank test and quantitative parameters were compared with paired t test and Bland-Altman analysis. RESULTS IMS-EPI demonstrated better image quality than SS-EPI for all aspects evaluated (SS-EPI vs. IMS-EPI: overall quality 3.04 vs. 4.17, artifacts 3.09 vs. 3.99, sharpness 2.40 vs. 4.32, lesion conspicuity 3.20 vs. 4.25; p < 0.001). Good agreement and correlation were observed between two reviewers (SS-EPI κ 0.699, r 0.742; IMS-EPI κ 0.702, r 0.789). IMS-EPI showed lower geometric distortion, SNR, and CNR than SS-EPI (p < 0.050). There was no significant difference in the mean ADC between the two sequences. CONCLUSION IMS-EPI showed better image quality with lower geometric distortion without affecting the quantification of ADC, though the SNR and CNR decreased due to post-processing limitations. KEY POINTS • IMS-EPI showed better image quality than SS-EPI. • IMS-EPI showed lower geometric distortion without affecting ADC compared with SS-EPI. • The SNR and CNR of IMS-EPI decreased due to post-processing limitations.

Abstract
Adenomyosis is frequently called the "forgotten" diagnosis, because of its non-characteristic clinical appearance. Similar to fibroid symptoms, adenomyosis may be the cause of disabling symptoms such as heavy menstrual bleeding, in particular pain (abdominal-, pelvic-, low back- and menstrual pain), with or without bulk related symptoms and fertility issues in premenopausal women. The current literature demonstrates durable symptom improvement in patients with adenomyosis following uterine artery embolisation. It is no longer justified to withhold women the option of uterine artery embolisation for symptomatic adenomyosis with or without fibroids.

Abstract
The coexistence of endometrial adenocarcinoma and adenomyosis in the same uterus is a common phenomenon. In many of such affected patients foci of adenomyosis could also be colonized by adenocarcinoma. The various permutations arising from these scenarios pose preoperative imaging and postoperative pathologic staging challenges. This article aims to raise awareness of these staging issues and lists some of the relevant practical approaches. Adenomyosis reduces the accuracy of magnetic resonance imaging in assessing the depth of invasion as it reduces the contrast between the endometrial cancer adenomyosis-involved myometrium. The article also offers an alternate argument for staging cancers where myoinvasion is found deep in the myometrium, arising from cancer-positive adenomyotic foci when the surface tumor is either limited to the endometrium or to the inner half of myometrium.

Abstract
Historically, cancer treatment has emphasized measures for the "cure" regardless of the long-term consequences. Advances in cancer detection and treatment have resulted in improved outcomes bringing to the fore various quality of life considerations including future fertility. For many young cancer patients, fertility preservation is now an integral component of clinical decision-making and treatment design. Optimal fertility-sparing options for young patients with gynecologic cancer are influenced by patient age, primary cancer, treatment regimens, and patient preferences. Possible approaches include embryo or oocyte cryopreservation, ovarian transposition, conservative surgery, and conservative medical treatment to delay radical surgery. These may be used alone or in combination to maximize fertility preservation. Awareness of the various fertility-sparing options, eligibility criteria, and the central role of magnetic resonance imaging in the proper selection of patients will enable radiologists to produce complete clinically relevant imaging reports and serve as effective consultants to referring clinicians. Knowledge of the potential imaging pitfalls is essential to avoid misinterpretation and guide appropriate management.

Abstract
PURPOSE To compare the diagnostic ability of reduced FOV diffusion-weighted (DW) MR imaging with that of 3D dynamic contrast-enhanced (DCE) MR imaging in evaluating the depth of myometrial invasion in patients with endometrial cancer. METHODS Three tesla MR images including T2-weighted imaging, reduced FOV DW imaging and 3D DCE MR imaging in sagittal and oblique axial (short axis) planes in 25 women with surgically proven endometrial cancer were retrospectively evaluated. The depth of myometrial invasion (stage S: < 50% vs stage D: ≥ 50%) on MR imaging was correlated with surgical pathology results. RESULTS The 25 endometrial cancers included 16 stage S and 9 stage D tumors. The depth of myometrial invasion could be accurately evaluated in 68% of the cases for T2-weighted imaging, 92% for 3D DCE MR imaging, and 96% for reduced FOV DW imaging. In two patients with coexisting adenomyosis, both T2-weighted imaging and 3D DCE MR imaging failed to reveal the deep myometrial invasion, and reduced FOV DW imaging clearly demonstrated the tumor margin in the cases. Combination of reduced FOV DW imaging reading together with T2-weighted imaging improved the assessment of myometrial invasion with a diagnostic accuracy of up to 100%. CONCLUSIONS Addition of reduced FOV DW imaging may improve the staging accuracy of MR imaging for endometrial cancer in assessing the depth of myometrial invasion. Especially, reduced FOV DW imaging has an advantage in assessing the depth of myometrial invasion for patients with coexisting adenomyosis. Reduced FOV DW imaging can be an alternative to 3D DCE MR imaging in evaluating myometrial invasion of endometrial cancer without the use of contrast medium.

Abstract
PURPOSE To compare the clinical usefulness of reduced field-of-view diffusion-weighted imaging (rFOV) with other imaging techniques in determining the depth of myometrial invasion (DMI) in endometrial cancer. MATERIALS AND METHODS In this prospective study we reviewed 3T magnetic resonance images of 51 patients with clinical Stage I endometrial cancer who underwent total abdominal hysterectomy with bilateral salphingoopherectomy within 3 days after imaging. rFOV with apparent diffusion coefficient reconstruction was obtained in three standard planes followed by sagittal T2 -weighted (T2 WI) images and 3D dynamic T1 -weighted and contrast-enhanced imaging (DCE MRI). Two radiologists with expertise in imaging gynecologic cancers evaluated images independently. The DMI was recorded on imaging and correlated with surgical pathology results. Sensitivity, specificity, positive predictive value, negative predictive value, and accuracy for DMI were calculated (<50% vs. >50%). RESULTS Compared with sagittal T2 WI + DCE MRI, rFOV imaging yielded greater specificity (82.2% vs. 90.0%, positive predictive value (42.8% vs. 60.0%), and accuracy (84.0% vs. 92%) for DMI determined by reader 1 and greater the sensitivity (83.3% vs. 100%) for DMI determined by reader 2. The error of measurement of DMI as a continuous variable in millimeters did not differ significantly between the rFOV and pathology results (P < 0.21). However, there was a statistically significant difference for the DMI measured on the dynamic sequence. The DMI on DCE was greater than that seen on pathology at P = 0.02. CONCLUSION rFOV can be used to assess DMI in clinical Stage I endometrial cancer.

Abstract
Dynamic-contrast enhanced (DCE) and diffusion-weighted (DW) MR imaging are invaluable in the detection, staging, and characterization of uterine and ovarian malignancies, for monitoring treatment response, and for identifying disease recurrence. When used as adjuncts to morphologic T2-weighted (T2-W) MR imaging, these techniques improve accuracy of disease detection and staging. DW-MR imaging is preferred because of its ease of implementation and lack of need for an extrinsic contrast agent. MR spectroscopy is difficult to implement in the clinical workflow and lacks both sensitivity and specificity. If used quantitatively in multicenter clinical trials, standardization of DCE- and DW-MR imaging techniques and rigorous quality assurance is mandatory.

Abstract
OBJECTIVE To investigate the oncologic and reproductive outcomes after progestin treatment of complex endometrial hyperplasia (CEH) and grade 1 endometrial carcinoma (EC). METHODS In a retrospective study, data were obtained for patients aged 20-42years with CEH or grade 1 EC at presumed stage IA (without myometrial invasion) who wished to preserve fertility and were treated at the Peking Union Medical College Hospital, China, between January 1, 2000, and December 31, 2011. Patients had received oral medroxyprogesterone acetate (250-500mg/day) or megestrol acetate (160-480mg/day) for at least 6months. Response to progestin treatment was assessed histologically. RESULTS Among 53 included patients, 39 (74%) achieved complete response after a median period of 6 (3-24) months. Complete response was less frequent among obese than nonobese patients (4/12 [33%] vs 35/41 [85%]; P=0.001). Disease recurrence was recorded in 10 (26%) patients with complete response; the 5-year recurrence-free survival rate was 71%. Among the 33 patients who retained a desire to conceive, 17 (52%) became pregnant. CONCLUSION Fertility-sparing management with oral progestin is effective. Obesity is associated with a lower probability of long-term success.

Abstract
Benign and malignant uterine masses can be seen in the women. Some of these are asymptomatic and incidentally discovered, whereas others can be symptomatic. With the soft tissue contrast resolution magnetic resonance imaging can render a definitive diagnosis, which can further help streamline patient management. In this article we show magnetic resonance imaging examples of benign and malignant masses of the uterus and their treatment strategies.

Abstract
Benign uterine disease is a common entity affecting women of all ages. Ultrasound has historically been the predominant imaging method used in the evaluation of benign gynaecological disease, magnetic resonance imaging (MRI) being reserved for use in the staging of malignant uterine and cervical disease. MRI is now increasingly used in the diagnosis of benign uterine disease as well as a tool for problem-solving in cases of diagnostic dilemma. It allows detailed assessment of benign conditions, such as endometrial lesions, leiomyomas, and adenomyosis, and can be helpful in the stratification of patients to different treatment modalities, including surgical resection, uterine artery embolization, and medical therapies. In this article, we review the MRI findings in the common benign uterine diseases.

Abstract
Endometrial cancer is staged according to the International Federation of Gynecology and Obstetrics surgical system. Clinical estimation of stage, however, can be inaccurate in more than 20%, and therefore, preoperative imaging of the disease may assist in planning the optimal course of treatment. Magnetic resonance imaging (MRI) may detect gross myometrial extension or extension of tumor to the cervical stroma, which can alter management and therefore help in preoperative surgical planning. This issue is increasingly relevant as less invasive surgical techniques, such as laparoscopic surgeries, are becoming more commonplace for lower stage cancers. Currently, MRI is the most widely used modality for preoperative planning.

Abstract
Adenomyosis is a pathological gynaecological condition characterised by benign invasion of the endometrium into the myometrium. It is often misdiagnosed, or is not easily recognised, although it is responsible for disabling symptoms such as menorrhagia, abnormal uterine bleeding, dysmenorrhoea and infertility in premenopausal women. The aim of this pictorial review is to analyse the features of adenomyosis by illustrating the most usual and typical imaging patterns, along with the unusual appearances, seen in a vast array of gynaecological imaging modalities. The different findings of focal and diffuse adenomyosis along with the diagnostic limitations of ultrasound, hysterosalpingography and magnetic resonance imaging are described, as are the pitfalls and differential diagnosis with other pathological conditions that are often misdiagnosed as adenomyosis. The role of the different imaging modalities in planning appropriate treatment and their usefulness in monitoring therapy are also discussed.

Abstract
Patients with gynecologic malignancies are evaluated with a combination of imaging modalities including ultrasonography (US), computed tomography (CT), and magnetic resonance (MR) imaging. US has a primary role in detecting and characterizing endometrial and adnexal pathology. CT is one of the primary modalities in staging malignancy and detecting recurrence. MR imaging is characterized by superior contrast resolution and specificity. This article reviews the role of radiologic imaging for the characterization of gynecologic masses and for staging, planning, and monitoring treatment, as well as for the assessment of tumor recurrence of the most common gynecologic malignancies.

Abstract
Common benign gynaecological diseases, such as leiomyoma, adenomyosis, endometriosis, and mature teratoma, rarely undergo malignant transformation. Benign transformations that may mimic malignancy include benign metastasizing leiomyoma, massive ovarian oedema, decidualization of endometrioma, and rupture of mature teratoma. The aim of this review is to provide a contemporary overview of imaging findings in malignant and apparent malignant transformation of benign gynaecological disease.

Abstract
The surgical treatment of endometrial malignancy is based on pre-operative assessment of differentiation, myometrial and lymph node infiltration. Studies have reported the use of magnetic resonance imaging (MRI) with conflicting results. This study aims to review the pre-operative accuracy of MRI against the histology in endometrial cancer within a district hospital. A total of 112 women were identified from January 1997 to December 2004. The post-operative FIGO staging showed 76.2% Stage I, 7.6% Stage II, 14.3% Stage III and 1.7% Stage IV. A total of 57% (n = 60) had a pre-operative MRI. The myometrial infiltration was difficult to interpret in 31 MRIs. The time between hysteroscopy and MRI scan in those cases was shorter (Mean 3 weeks, SD +/- 1.5) than in reports with a clear interpretation (4.4 weeks, SD +/- 1.6). Sensitivity for MRI to detect deep myometrial infiltration was 35.7% (5/14) and specificity 50% (23/46). Accuracy was 46.6% (28/60). The presented data suggests a poor predictability of myometrial invasion by MRI but the numbers are small and MRI is a rapidly evolving modality. The conclusions must be treated with caution and cannot easily be applied to large gynaecological cancer units in general.

Abstract
The purpose of this study was to define guidelines for endometrial cancer staging with MRI. The technique included critical review and expert consensus of MRI protocols by the female imaging subcommittee of the European Society of Urogenital Radiology, from ten European institutions, and published literature between 1999 and 2008. The results indicated that high field MRI should include at least two T2-weighted sequences in sagittal, axial oblique or coronal oblique orientation (short and long axis of the uterine body) of the pelvic content. High-resolution post-contrast images acquired at 2 min +/- 30 s after intravenous contrast injection are suggested to be optimal for the diagnosis of myometrial invasion. If cervical invasion is suspected, additional slice orientation perpendicular to the axis of the endocervical channel is recommended. Due to the limited sensitivity of MRI to detect lymph node metastasis without lymph node-specific contrast agents, retroperitoneal lymph node screening with pre-contrast sequences up to the level of the kidneys is optional. The likelihood of lymph node invasion and the need for staging lymphadenectomy are also indicated by high-grade histology at endometrial tissue sampling and by deep myometrial or cervical invasion detected by MRI. In conclusion, expert consensus and literature review lead to an optimized MRI protocol to stage endometrial cancer.

Abstract
OBJECTIVE In this study, the authors discussed the feasibility and value of diffusion-weighted (DW) MR imaging in the detection of uterine endometrial cancer in addition to conventional nonenhanced MR images. METHODS AND MATERIALS DW images of endometrial cancer in 23 patients were examined by using a 1.5-T MR scanner. This study investigated whether or not DW images offer additional incremental value to conventional nonenhanced MR imaging in comparison with histopathological results. Moreover, the apparent diffusion coefficient (ADC) values were measured in the regions of interest within the endometrial cancer and compared with those of normal endometrium and myometrium in 31 volunteers, leiomyoma in 14 patients and adenomyosis in 10 patients. The Wilcoxon rank sum test was used, with a p<0.05 considered statistically significant. RESULTS In 19 of 23 patients, endometrial cancers were detected only on T2-weighted images. In the remaining 4 patients, of whom two had coexisting leiomyoma, no cancer was detected on T2-weighted images. This corresponds to an 83% detection sensitivity for the carcinomas. When DW images and fused DW images/T2-weighted images were used in addition to the T2-weighted images, cancers were identified in 3 of the remaining 4 patients in addition to the 19 patients (overall detection sensitivity of 96%). The mean ADC value of endometrial cancer (n=22) was (0.97+/-0.19)x10(-3)mm(2)/s, which was significantly lower than those of the normal endometrium, myometrium, leiomyoma and adenomyosis (p<0.05). CONCLUSION DW imaging can be helpful in the detection of uterine endometrial cancer in nonenhanced MR imaging.

Abstract
Endometrial cancer is the second most common gynaecological malignancy. The usual presentation with post-menopausal bleeding results in an early diagnosis in most cases and thus there is opportunity for cure. Magnetic resonance (MR) imaging is pivotal in the decision-making process regarding treatment options. We present a review of the magnetic resonance (MR) findings to illustrate its role in the staging of endometrial cancer.

Abstract
Magnetic resonance (MR) imaging is a highly accurate non-invasive technique for the diagnosis of adenomyosis. Typical MR features include either diffuse or focal thickening of the junctional zone or an ill-defined area of low signal intensity in the myometrium on T2-weighted MR images. Occasionally, the islands of ectopic endometrial tissue can be identified as punctate foci of high signal intensity. Less commonly, adenomyosis can present as a well-circumscribed form known as adenomyoma, adenomyotic cyst characterized by the presence of haemorrhagic cyst, or adenomyomatous polyp protruding into the uterine cavity. The MR appearances of adenomyosis may occasionally fluctuate in response to hormonal stimulation and treatment. MR imaging is helpful not only in monitoring the treatment effect of hormonal therapy, but also in predicting therapeutic effect. In cases of endometrial cancer in the uterus with adenomyosis, evaluation of myometrial invasion may become difficult. Rarely, endometrial cancer may arise directly from adenomyosis resulting from malignant transformation of endometrial glands, creating diagnostic challenges. Differential diagnosis of adenomyosis on MR imaging include physiological myometrial contraction and almost all myometrial lesions, and they should be carefully differentiated from adenomyosis by identifying typical clinical and MR features in these lesions. Precise knowledge of the spectrum of MR features in adenomyosis greatly helps in determining an accurate diagnosis and appropriate management of the patients.

Abstract
Adenomyosis is a nonneoplastic condition, characterized by benign invasion of ectopic endometrium into the myometrium with hyperplasia of adjacent smooth muscle. The common symptoms include dysmenorrhea, menorrhagia, and abnormal uterine bleeding, but these do not allow diagnosis. Therefore, imaging plays an important role because establishment of the correct preoperative diagnosis is critical to avoid unnecessary intervention. Magnetic resonance (MR) imaging is a highly accurate noninvasive modality for diagnosis of adenomyosis, differentiation of adenomyosis from other gynecologic disorders, and planning of appropriate treatment. Although the typical MR imaging findings are well established, adenomyosis actually varies widely in terms of histopathologic features (adenomyosis with sparse glands), growth patterns (polypoid adenomyoma, adenomyotic cyst, and miniature uterus), responses to hormonal activity (tamoxifen, decidual changes), and responses to treatment (gonadotropin-releasing hormone agonist). The MR imaging findings of adenomyosis occasionally mimic those of uterine malignancy or ovarian cancer. Furthermore, malignancy occasionally develops in otherwise benign adenomyosis. Pitfalls in diagnosis of adenomyosis include myometrial contractions, leiomyoma, adenomatoid tumor, metastases, endometrial carcinoma, and endometrial stromal sarcoma. Knowledge of the various appearances of adenomyosis and the possible pitfalls in differential diagnosis help guide the determination of appropriate treatment options.

Abstract
BACKGROUND Magnetic resonance imaging (MRI) is reported to offer the best imaging of local disease in endometrial cancer. We audited MRI scans to identify their clinical utility, particularly in the preoperative identification of 'low risk' endometrial cancer (grade one or two endometrioid tumours confined to the inner half of the myometrium). AIM To correlate histological and MRI findings and to establish our ability to preoperatively identify women with 'low risk' tumours. STUDY DESIGN A retrospective audit of MRI scans in women with a new diagnosis of endometrial cancer from July 1998 to November 2002. Radiology and pathology reports and surgical staging data were extracted. Independently a team of radiologists reviewed MRI films and the findings were compared to pathology. RESULTS Thirty-nine patients were included. Only 10% of original reports contained all the clinically relevant information. On review, the sensitivity for the detection of myometrial invasion was 90%, specificity 71%, positive predictive value (PPV) 93% and negative predictive value (NPV) 63%. For the detection of deep invasion, sensitivity was 56%, specificity 77%, PPV 64% and NPV 71%. All women with grade one or two tumours having no invasion or grade one having superficial invasion detected on MRI had pathological 'low risk' disease. CONCLUSIONS Magnetic resonance imaging scans as reported offered limited clinical benefit. Attention needs to be given to MRI sequencing and reporting protocols. If the review results can be confirmed by prospective studies, MRI offers significant clinical utility in the identification of low risk patients and their surgical treatment planning.
