To evaluate the number and characteristics of papers on MR imaging written by radiologists in Spain and published in 2001-2007 Medline-indexed journals, including a comparison with the MR research output from German radiological departments. ⋯ Spanish radiologists published approximately two-third of their MR articles in several non-Spanish journals, while the official Spanish radiological journal Radiología leads the ranking of Spanish journals. Spanish radiologists are mainly active in the "neuroradiology" topic. The Spanish healthcare sector is the most active. German institutions published more in their official journal ROFO.

The relation between lung perfusion defects and intravascular clots in acute pulmonary thromboembolism (PTE) was comprehensively assessed on deep-inspiratory breath-hold (DIBrH) perfusion SPECT-computed tomographic pulmonary angiography (CTPA) fusion images. ⋯ Because of unexpected dissociation between intravascular clots and lung perfusion defects, the present fusion images will be a useful adjunct to CTPA in the diagnosis of acute PTE.

Blunt trauma to pancreas is uncommon and clinical features are often non-specific and unreliable leading to possible delays in diagnosis and therefore increased morbidity. CT has been established as the imaging modality of choice for the diagnosis of abdominal solid-organ injury in the blunt trauma patient. ⋯ The CT appearance of pancreatic injury ranges from a normal initial appearance of the pancreas to active pancreatic bleeding. Knowledge of CT signs of pancreatic trauma and a high index of suspicion is required in diagnosing pancreatic injury.

To assess the added value of T2-weighted MRI to gadolinium-enhanced dynamic MRI for detection of HCCs. ⋯ The addition of T2-weighted imaging to gadolinium-enhanced 3D dynamic imaging could be helpful in the detection of HCC by increasing reader confidence for HCCs with equivocal findings on gadolinium-enhanced MRIs.

Spectral appearance and concentrations of the most prominent metabolites are affected by brain development. This knowledge is essential for the detection of pathological changes in pediatric patients. ⋯ Clinical examples show several diseases that are reflected in changes in (1)H MR spectra due to pathological alterations in the biochemical pathways of the observed metabolites. Attention is given to the main metabolites such as N-acetylaspartate, creatine/phosphocreatine, cholines, lactate, inositol, etc.
