A deficit of vitamin B12, generally resulting from pernicious anaemia, can give rise to disorders of the spinal cord, brain, optic and peripheral nerves. The principal neurological syndrome is subacute combined degeneration of the spinal cord (SCD), which can cause progressive motor and/or sensitive alterations, instability and incontinency, due to the demyelination of the posterior horn of the spinal cord. The identification by magnetic resonance (MR) of signal hyperintensity in T2 weighted sequences at the level of the posterior horns of the spinal and/or cervical cord can be of great use in diagnosising the patient with SCD, above all when the symptoms are mild or nonspecific, and the patient does not have haematological or gastrointestinal alterations.

Background: Epicardial adipose tissue (EAT) is an important indicator of cardiovascular risk. This parameter is generally assessed on ECG-gated computed tomography (CT) images.

Purpose: To evaluate feasibility and reliability of EAT quantification on non-gated thoracic low-radiation-dose CT examinations with respect to prospectively ECG-gated cardiac CT acquisition.

Objective: To compare two series of patients with breast cancer, one staged using preoperative MRI and the other staged using conventional techniques, analyzing the changes to treatment, the number of mastectomies, and the number of reinterventions due to involvement of the margins.

Material And Methods: We reviewed 600 patients divided into 300 patients with preoperative MRI (series 1) and 300 without preoperative MRI (series 2). We recorded the following variables: age, menopausal status, tumor size on pathological examination, multiplicity and bilaterality, surgical treatment and type of treatment, the administration of neoadjuvant chemotherapy, and reintervention for involved margins.

The replacement of conventional films and view boxes with digital images and computer monitors managed by PACS has clearly improved the diagnostic imaging workplace. The new setup has many advantages, including increased productivity brought about by decreased overall time required for image interpretation. On the other hand, the implementation of the digital workplace has increased the importance of factors like background lighting and the position of the chair, work table, mouse, keyboard, and monitor to prevent lesions that can disable the radiologist.
