ABSTRACT
Significant progress has been made with the introduction of the TNM-7 staging system for non-small cell lung cancer (NSCLC). Constituting the first major revision in 12 years, the seventh edition of NSCLC TNM (TNM-7) is based on the recommendations from the International Association for the Study of Lung Cancer (IASLC) Lung Cancer Staging Project of 2007. This new TNM iteration includes a subset analysis on SCLC and carcinoid tumors. A thorough understanding of its principles by the radiologist is helpful to increase efficiency and to improve communication with the referring clinicians.

We report the clinical, MR imaging, and proton MR spectroscopy findings in a middle-aged woman with proved methadone-induced toxic leukoencephalopathy. The imaging characteristics of this unusual condition have been reported only rarely in the medical literature. We show that the imaging findings in methadone-induced toxic leukoencephalopathy are similar, though not identical, to previously reported cases of neurologic deterioration due to heroin inhalation.

The past decade there has been an enormous advance in imaging technology, most obvious in the field of magnetic resonance imaging (MRI) and computed tomography (CT). Today nearly every radiology department has a multislice CT (MSCT) available for routine imaging, many of which are increasingly being replaced by last generation 16- and 64-slice CT scanners. However, the use of fast CT scanners requires a better insight in acquisition and contrast media injection protocols in order to achieve the best possible result. It is the aim of this article to give a review of the basic principles of CT protocol design for the chest and the kinetics of contrast media injection.

Injuries to the sternoclavicular joint are an uncommon problem, but can be life-threatening if not diagnosed and treated properly. Both anterior and posterior sternoclavicular dislocations or subluxations can occur, the latter being a rare injury. In this case report we report the imaging findings of both conventional radiography and multidetector CT on a 16-year-old man who developed a posterior sternoclavicular dislocation while participating in a football match. The current literature regarding this subject is also reviewed.
