“…Similar results were reported by Aoki et al [23] in a study including 30 patients. Published data show that the best modality for detection of parametrial invasion is MRI with an accuracy of 92% reported by Kim et al [24] and 88% reported by Hrickak et al [25].…”

Aims: The aim of this study was to evaluate the use of pre and post-therapy transrectal and transvaginal ultrasonography (TRUS, TVUS) with contrast enhancement and strain elastography compared with clinical examination and magnetic resonance imaging (MRI) in the assessment of advanced stage cervical cancer. Material and methods: This was a prospective study, carried out over a period of nine months on subjects with advanced-stage cervical cancer (stage ≥IIB). All included patients were examined clinically and underwent abdomino-pelvic contrast enhanced MRI and multimodal US examinations (TRUS with strain elastography and contrast enhanced TVUS) at the time of diagnosis and after radiochemotherapy. Tumor size and staging at TRUS and TVUS was compared with the same data obtained by clinical examination and MRI. Pathology was the golden standard. Results: Eight patients accomplished the inclusion criteria. In five cases the tumor stage was identical on clinical and MRI examinations. In all cases parametrial infiltration was diagnosed by all pre-treatment examinations. No significant differences were observed in tumor size between clinical, US and MRI exams either at baseline or post-therapy, in native or post-contrast examinations. The size of the tumor evaluated pre-treatment proved to be significantly smaller post-contrast in both US and MRI examinations compared with the native images. Post-therapy, no significant differences were observed on US measured tumor dimensions when comparing native with post-contrast images. Oppositely, significant smaller dimensions were observed on post-contrast MRI compared with native scans. Conclusions: TRUS is accurate in the estimation of pre-therapy cervical cancer dimension. The post therapy tumor evaluation is better performed with MRI. The use of intravenous contrast agents on both examinations did not improved the accuracy of tumor evaluation pre-or post-therapy.

“…Medicine ' SMRI. 1993 Robert Lotocki, MD MAGNETIC RESONANCE (MR) IMAGING is well established in the investigation of endometrial and cervical cancer (1)(2)(3)(4)(5)(6)(7). The role of MR imaging in the investigation of ovarian cancer has been more limited, in part because conventional spin-echo sequences have long acquisition times and images have decreased spatial and contrast resolution relative to computed tomographic (CT) scans, which renders detection of small peritoneal metastases difficult (8).…”

Sixteen patients with clinically suspected malignant ovarian disease underwent contrast agent-enhanced computed tomography (CT) and magnetic resonance (MR) imaging in a prospective comparative study. MR imaging included fat-suppressed spin-echo and breath-hold FLASH (fast low-angle shot) before and after intravenous injection of gadopentetate dimeglumine. Histologic confirmation was obtained at laparotomy (n = 13) and biopsy (n = 3). Thirteen patients had histologically proven primary ovarian cancer. MR images showed the internal architecture of ovarian tumors better than CT in nine patients and equivalently in seven. MR images showed the relationship between ovarian tumors and adjacent pelvic structures (uterus [n = 9], sigmoid colon [n = 7], bladder [n = 7], and rectum [n = 3]) better than CT in nine patients and equivalently in seven. Intraabdominal extent of disease was better defined on MR than on CT images in nine patients, equivalently in six, and worse in one. Peritoneal metastases 1-2 cm in diameter were detected on MR images and missed on CT scans in six patients. In only one case did this result in a staging error with CT. The results suggest that MR imaging is at least equivalent and may be superior to CT in the evaluation of ovarian malignancy.

Objectives: To retrospectively evaluate the value of CT for lymph node (LN) staging in bladder cancer. Methods: Two uroradiologists reviewed CT scans of 231 patients who underwent radical cystectomy and pelvic lymphadenectomy according to a predefined 12-field template. A 5-step model was used to grade the radiological likelihood of a LN to represent malignant spread based on size, configuration and structure as well as regional clustering. Statistical analyses were performed both on patient- and field-based levels. Results: LN metastases were found in 59 of 231 patients (25.5%). On a patient-based level, sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV) and accuracy were 52.6, 93.6, 73.2, 85.6 and 83.4%, respectively. Using the field-based approach, a total of 1,649 anatomical fields were evaluable, of which 114 fields showed malignancy (6.9%). On a field basis, sensitivity, specificity, PPV, NPV and accuracy were 30.2, 98, 51.5, 94.5 and 93.3%, respectively. Concerning local staging (pT category), the overall accuracy was 78%; overstaging occurred in 6% and understaging in 16%. Conclusions: In line with prior studies, the sensitivity of CT imaging for the detection of LN metastases was low, while high values for specificity were achieved. This was further underlined by analyzing standardized anatomical fields. Concerning local staging, postoperative changes after TURB-T rarely led to overstaging.
