Absence of clinical benefit of FDG PET-CT in staging T1 part-solid lung adenocarcinoma.

Aim: To assess the rates of nodal and metastatic disease and change in management when staging part-solid T1 lung adenocarcinomas using integrated 2-[F]-fluoro-2-deoxy-d-glucose (FDG) positron-emission tomography (PET)-computed tomography (CT) in a UK population.

Materials And Methods: This was a retrospective review of PET-CT examinations performed to stage radiologically suspected T1 part-solid lung adenocarcinoma (n=58) from two different centres. Rates of detection of nodal and metastatic disease, change in management, and final patient outcome were recorded.

Identification of specific SUVmax ratios enhances diagnostic accuracy for staging of intrathoracic nodes in lung cancer.

Introduction: Studies demonstrating limited accuracy of 'positive' and 'negative' lymph nodes on fluorodeoxyglucose (FDG) PET-CT in staging for lung cancer have led to guidelines stating mediastinal nodes enlarged on computed tomography, irrespective of FDG uptake, require endobronchial ultrasound (EBUS)-transbronchial needle aspiration (TBNA). However FDG uptake occurs on a continuous spectrum and the use of standardised uptake value (SUV)max ratios, rather than a binary classification, may have improved diagnostic accuracy.

Methods: This was a retrospective analysis of patients with lung cancer who had PET-CT and EBUS-TBNA in 2015-2018.

Scintimammography: a pictorial review of the variable normal, post surgical and pathological appearances.

Scintimammography has a high specificity and sensitivity for the detection of primary and metastatic breast carcinoma and in the evaluation of the postoperative breast. This review highlights the spectrum of pathological features as well as the normal postoperative and postreconstruction changes and the variable normal appearances that may be encountered with this technique.
