“…Moreover, contrast-enhanced MRI may improve the specificity of the optimal criteria. In the present study, the accuracy, specificity and sensitivity on MRI were low compared with those reported by Wang et al[ 9]. The patients enrolled in our study were those in whom the tumor made contact with the entire trachea.…”

“…The adventitia was too thin to identify on MRI. Wang et al [9] combined the predictors of soft tissue in the cartilage, intraluminal mass and involvement ≥180° on MRI findings to detect the direct invasion. When any of these combined criteria was positive, accuracy was 90% with 100% sensitivity and 84% specificity.…”

“…Thus, accuracy, sensitivity and specificity were low. In the report by Wang et al[ 9], the patients with tumor involvement ≥180° on MRI showed low sensitivity. Therefore, MRI was not sufficient to predict the precise depth of tumor invasion into the trachea.…”

Usefulness of Preoperative Endobronchial Ultrasound for Airway Invasion around the Trachea: Esophageal Cancer and Thyroid Cancer

Background: It is important to confirm preoperative tracheobronchial invasion to enable the selection of the most appropriate treatment. Objective: This study was performed to compare the usefulness of computed tomography (CT), magnetic resonance image (MRI) and bronchoscopy by endobronchial ultrasonography (EBUS) for the assessment of invasion of thyroid or esophageal cancer in cases with suspected tracheobronchial invasion. Methods: In cases with suspected contact between the tumor and tracheobronchial wall, CT, MRI and EBUS indicated deformity of the tracheobronchial wall due to the adjacent mass. The final diagnosis was based on surgical and histological results, and/or clinical follow-up. Results: Fifty-four patients were included in this study. Based on the findings of CT, MRI and EBUS, invasion was suspected in 29, 28 and 25 patients, respectively. Seventeen patients did not undergo surgery based on the results of CT, MRI and bronchoscopy with EBUS. Final diagnosis was intact trachea or bronchial adventitia in 26 patients and invasion in 28 patients. The sensitivity and specificity of CT, MRI and EBUS for invasion were 59 and 56, 75 and 73, and 92 and 83%, respectively. The accuracy of EBUS was significantly greater than that of CT in the present study (p = 0.0011). The accuracy of EBUS was significantly different from that of CT and MRI in the surgically treated patients (p = 0.005 and p = 0.032, respectively). Conclusion: EBUS is the most useful technique for determining the depth and extent of tumor invasion into the airway wall. The combination of MRI and EBUS will contribute to surgical planning in patients with esophageal and thyroid cancer.

“…It offers excellent soft-tissue contrast, which is particularly useful when esophageal and/or tracheal invasion is suspected (54,55). Although its specificity is relatively low (51%), MRI offers excellent sensitivity (95%) for the detection of metastatic lymphadenopathy in DTC patients (56).…”

The clinical and epidemiological profiles of differentiated thyroid cancers (DTCs) have changed in the last three decades. Today's DTCs are more likely to be small, localized, asymptomatic papillary forms. Current practice is, though, moving toward more conservative approaches (e.g. lobectomy instead of total thyroidectomy, selective use of radioiodine). This evolution has been paralleled and partly driven by rapid technological advances in the field of diagnostic imaging. The challenge of contemporary DTCs follow-up is to tailor a risk-of-recurrence-based management, taking into account the dynamic nature of these risks, which evolve over time, spontaneously and in response to treatments. This review provides a closer look at the evolving evidence-based views on the use and utility of imaging technology in the post-treatment staging and the short-and long-term surveillance of patients with DTCs. The studies considered range from cervical US with Doppler flow analysis to an expanding palette of increasingly sophisticated second-line studies (cross-sectional, functional, combined-modality approaches), which can be used to detect disease that has spread beyond the neck and, in some cases, shed light on its probable outcome.

Tracheal Invasion by Thyroid Carcinoma

Abstract: Tracheal invasion by thyroid carcinomas can be accurately diagnosed with MR imaging, and using a combination of criteria is the most accurate method of predicting this phenomenon.
