Accuracy of (18) FDG PET-CT for treatment evaluation 3 months after completion of chemoradiotherapy for head and neck squamous cell carcinoma: 2-year minimum follow-up.

Background: The purpose of this study was to assess the accuracy of (18) F-fluorodeoxyglucose positron emission tomography ((18) FDG PET)-CT in detecting residual or recurrent disease after nonsurgical treatment for head and neck squamous cell carcinoma (HNSCC).

Methods: We conducted a retrospective analysis of patients with oral cavity, oropharynx, larynx, hypopharynx, or cervical lymph node location of SCC treated with chemoradiotherapy. Twelve weeks posttreatment, (18) FDG PET-CT results were compared to histology if residual disease was suspected.

Comparative effectiveness of [(18) F]-fluorocholine PET-CT and pelvic MRI with diffusion-weighted imaging for staging in patients with high-risk prostate cancer.

Background: Accurate staging is important before surgical decision in patients with high-risk prostate cancer (PCa). The purpose of this study was to prospectively compare the diagnostic performance of (18) F-FCholine and MRI with diffusion weighted imaging (DWIMRI) for local and regional lymph node (LN) staging before radical prostatectomy (RP) with extended pelvic lymphadenectomy (PLND).

Methods: We identified 47 patients who underwent (18) F-FCholine and DWIMRI followed by surgical treatment (either prostatectomy or LN dissection or an association of prostatectomy and LN dissection) between May 2010 and December 2012 at Bordeaux University Hospital.

Unexpected coexisting myocardial infarction detected by delayed enhancement MRI.

We report a case of an unexpected coexisting anterior myocardial infarction detected by delayed enhancement MRI in a 41-year-old man following a presentation with a first episode of chest pain during inferior acute myocardial infarction. This second necrotic area was not initially suspected because there were no ECG changes in the anterior leads and the left descending coronary artery did not present any significant stenoses on emergency coronary angiography. Unrecognised myocardial infarction may carry important prognostic implications.
