2.  MRI and CT findings of metastatic pulmonary calcification 
The British Journal of Radiology  2012;85(1011):e069-e072.
Metastatic pulmonary calcification is a consequence of calcium deposition in the normal pulmonary parenchyma, secondary to abnormal calcium metabolism. The most characteristic radiological manifestation is poorly defined nodular opacities that are mainly seen in the upper lung zone. The aim of this report is to describe the CT and MRI findings observed in two patients with metastatic pulmonary calcification. The disease may present in CT as consolidations with calcification, and with a high lesion/muscle signal intensity ratio on T1 weighted imaging without contrast in MRI. The high signal on T1 weighted imaging probably occurs because the low calcium concentration of the lesion changes the surface effects of diamagnetic calcium particles, causing T1 shortening of water protons. MRI is a good option for characterising calcium accumulation caused by a metabolic disorder.

3.  Large pulmonary masses containing varicose veins: a rare presentation of benign metastasising leiomyomas 
The British Journal of Radiology  2010;83(995):e243-e246.
A 48-year-old woman presented with cough and chest pain. A chest radiograph and CT scans showed bilateral lung masses containing massive venous varices. A core biopsy specimen revealed benign metastasising leiomyoma with strong expression of progesterone receptors. A review of her medical history revealed a hysterectomy 11 years earlier. The lung masses showed significant reduction in size after induction of artificial menopause, although the pulmonary varices persisted.

4.  Valsalva manoeuvre effect on distribution of lung damage in heroin inhalation 
The British Journal of Radiology  2011;84(1006):e200-e201.
This article reports the case of a patient demonstrating acute bilateral pneumonitis almost completely confined to the upper lobes as a result of inhaling heroin. We attribute this distribution to the patient performing the Valsalva manoeuvre immediately after inhaling heroin. This pattern has not been reported before and we believe it may be seen more frequently owing to a switch amongst drug users from intravenous to inhaled heroin.

5.  MRI in lung cancer: a pictorial essay 
The British Journal of Radiology  2011;84(1003):661-668.
Imaging studies play a critical role in the diagnosis and staging of lung cancer. CT and 18-fluorodeoxyglucose positron emission tomography CT (PET/CT) are widely and routinely used for staging and assessment of treatment response. Many radiologists still use MRI only for the assessment of superior sulcus tumours, and in cases where invasion of the spinal cord canal is suspected. MRI can detect and stage lung cancer, and this method could be an excellent alternative to CT or PET/CT in the investigation of lung malignancies and other diseases. This pictorial essay discusses the use of MRI in the investigation of lung cancer.

6.  Magnetic resonance imaging findings in acute pulmonary embolism 
The British Journal of Radiology  2011;84(999):282-287.
Pulmonary embolism (PE) is the third most common acute cardiovascular disease after myocardial infarction and stroke, and results in thousands of deaths each year. Improvements in MRI accuracy are ongoing with the use of parallel imaging for angiography techniques and pulmonary perfusion. This, associated with other potential advantages of MRI (e.g. a radiation free method and better safety profile of MR contrast media), reinforces its use. The aim of this paper is to perform a pictorial review of the principal findings of MRI in acute PE. Acute PE can manifest itself as complete arterial occlusion and the affected artery may be enlarged. We report the main vascular and parenchymal signs, and an overview of current literature regarding accuracy, limitations and technical aspects is provided.

7.  Ketorolac tromethamine associated with diffuse pulmonary haemorrhage: high-resolution CT findings 
The British Journal of Radiology  2010;83(991):e158-e160.
Drug-induced lung diseases are a frequent cause of morbidity. Diffuse pulmonary haemorrhage is an uncommon complication of drug therapy, and is a potentially life-threatening situation. We report the high-resolution CT and clinical findings of a 32-year-old man with diffuse pulmonary haemorrhage induced by ketorolac tromethamine.
