Screen-detected subsolid pulmonary nodules: long-term follow-up and application of the PanCan lung cancer risk prediction model.

Objective: To report the long-term follow-up of subsolid nodules (SSNs) detected in participants of a prospective low-dose CT lung cancer screening cohort, and to investigate the utility of the PanCan model in stratifying risk in baseline SSNs.

Methods: Participants underwent a baseline scan, two annual incidence scans and further follow-up scans for the detected nodules. All SSNs underwent a minimum of 2 years of follow-up (unless resolved or resected).

Queensland Lung Cancer Screening Study: rationale, design and methods.

Background: Lung cancer is the leading cause of cancer-related mortality in Australia. Screening using low-dose computed tomography (LDCT) can reduce lung cancer mortality. The feasibility of screening in Australia is unknown.

Bronchiolitis obliterans syndrome in lung transplant recipients: can thin-section CT findings predict disease before its clinical appearance?

Purpose: To determine whether there are thin-section computed tomographic (CT) features that predict bronchiolitis obliterans syndrome (BOS) in lung transplant recipients before the clinical appearance and during the early stages of the disease.

Materials And Methods: Two hundred ninety-eight thin-section CT scans obtained in 26 lung transplant recipients who did (study group) and 26 lung transplant recipients who did not (control group) develop BOS were reviewed for the presence of mosaic perfusion, bronchiectasis, bronchial wall thickening, and air trapping. BOS was defined by using the recently revised definition of the International Society for Heart and Lung Transplantation.

Pressure half-time predicts hemodynamically significant pulmonary regurgitation in adult patients with repaired tetralogy of fallot.

Pulmonary regurgitation (PR) is associated with adverse outcomes late after tetralogy of Fallot repair. Accurate assessment of PR in these patients is, therefore, fundamental to their clinical treatment; however, accurate ultrasound markers of severity are as yet poorly defined. This is a prospective study of 34 adult patients with repaired tetralogy of Fallot.

US of liver transplants: normal and abnormal.

Whole-liver transplantation is an accepted and successful method of treating end-stage liver disease. As a result of the shortage of cadaveric livers, split-liver transplantation and living donor liver transplantation are becoming more commonplace. Ultrasonography (US) is the initial imaging modality of choice for detection and follow-up of early and delayed complications from all types of liver transplantation.

Gamma-probe-guided resection of the sentinel lymph node in breast cancer.

Regional lymph node metastases in patients with breast cancer have fundamental staging, prognostic, and treatment implications. Classically, axillary lymph node sampling requires a dissection under general anesthesia. The concept that a primary, or sentinel, lymph node is the first node to receive drainage from a tumor has been established in patients with malignant melanomas using radiolabeled tracers and vital dyes.

Analysis of thyroid carcinoma in patients with cold thyroid nodules: a review.

It is generally accepted that the risk of thyroid carcinoma is more likely when solitary cold nodules are seen on a thyroid scan, while the presence of thyroid carcinoma in hyperfunctioning nodules has been found to be quite rare. This article attempts to establish the incidence of thyroid carcinoma in patients with solitary cold nodules on thyroid scans. The records of 110 consecutive patients who underwent thyroidectomy procedures were reviewed.
