A radiopaque polymer hydrogel used as a fiducial marker in gynecologic-cancer patients receiving brachytherapy.

Purpose: We assessed a novel Food and Drug Administration-approved hydrogel, synthesized as absorbable iodinated particles, in gynecologic-cancer patients undergoing computed tomography (CT) or magnetic resonance (MR) based brachytherapy after external beam radiation.

Methods And Materials: Nineteen patients underwent CT-guided (n = 13) or MR-guided (n = 6) brachytherapy for gynecologic cancers. Seventy-seven hydrogel injections were placed.

Demystifying NUT midline carcinoma: radiologic and pathologic correlations of an aggressive malignancy.

Objective: NUT midline carcinoma is a rare poorly differentiated aggressive subtype of squamous cell carcinoma. To date, fewer than 100 total cases have been reported.

Conclusion: Given the rarity of this disease process and lack of pathognomonic imaging findings, a definitive diagnosis based solely on imaging findings alone is untenable.

Dosimetric consequences of interobserver variability in delineating the organs at risk in gynecologic interstitial brachytherapy.

Purpose: To investigate the dosimetric variability associated with interobserver organ-at-risk delineation differences on computed tomography in patients undergoing gynecologic interstitial brachytherapy.

Methods And Materials: The rectum, bladder, and sigmoid of 14 patients treated with gynecologic interstitial brachytherapy were retrospectively contoured by 13 physicians. Geometric variability was calculated using κ statistics, conformity index (CIgen), and coefficient of variation (CV) of volumes contoured across physicians.

Clinical outcomes for gastric cancer following adjuvant chemoradiation utilizing intensity modulated versus three-dimensional conformal radiotherapy.

Purpose/objectives: To determine if intensity modulated radiation therapy (IMRT) in the post-operative setting for gastric cancer was associated with reduced toxicity compared to 3D conformal radiation therapy (3DCRT).

Materials/methods: This retrospective study includes 24 patients with stage IB-IIIB gastric cancer consecutively treated from 2001-2010. All underwent surgery followed by adjuvant chemoradiation.

The many faces of Behçet's disease.

A 23-year-old man with fevers, night sweats, lymphadenopathy, worsening vision, and aphthous ulcers was diagnosed with Behçet's disease. Multiple diagnostic imaging modalities were used to identify various multisystem complications associated with Behçet's disease including vascular thomboses, mediastinal fibrosis, chylothoraces, chylopericardium and coronary artery aneurysms.
