Medical image generating departments, typically radiology and nuclear medicine, have always been burdened by image management problems. Image management is the administration of imaging examination requests, the performance of imaging examinations, the distribution of the images and reports, the archiving of examinations and results and the retrieval of previous examinations and results. This is a very resource-intensive responsibility dependent on a long chain of human interaction that often fails.
Within both the public and private sectors this is a real problem. In the public sector increased efficiency is required to decrease the waiting lists and improve patient care. In the private sector improved productivity is required to increase the revenue generated by the same amount of human and financial resources. The solution is to embrace digital image management.
The solution does not lie within a single information system, but rather the tight integrations of four parts: digital imaging equipment, PACS (Picture Archiving and Communication System), RIS (Radiological Information System) and HIS (Hospital Information System)
This article aims to demystify some of the acronyms commonly used and explain their practical role within the classic imaging department.

Fat necrosis is a common benign condition. It is associated with iatrogenic, penetrating or blunt trauma. In a number of cases, there is no history of injury. Mammographic presentation is either a typical lipid cyst or a spiculated lesion, mimicking malignancy. Ultrasonographic appearance is that of either a cyst, or solid mass, or an area of increased echogenicity. Calcifications may be present and are usually coarse or ring-like.

Gas in the wall of the stomach is a rare condition and may be caused by gastric pneumatosis (also known as gastric emphysema) or emphysematous gastritis. We present the case of a 27-year-old white female patient with a history of thoracic and abdominal surgery who presented with intractable vomiting, clinically suspected to be as a result of gastric outlet obstruction. Intramural gastric air was subsequently demonstrated on plain abdominal X-rays, fluoroscopy (water-soluble contrast meal), and on an abdominal CT scan.

When encountering a radiologically benign lucent bone lesion in a child, a simple bone cyst is a reasonable diagnostic consideration. Simple or unicameral bone cysts are expansile, serous-fluid-containing defects, that are not true neoplasms. Peak age ranges between 3 and 14 years in 80% of cases.

Spinal catheter angiography is the gold standard for diagnosing and treating vascular abnormalities, however selective catheterisation of the spinal arteries is a highly technical, laborious, invasive and expensive process. The procedure also has minor and major complications related to the intervention.
