We aimed to determine the degree and extent of parenchymal abnormalities on pulmo-CT in patients with emphysema. The study group consisted of 29 patients (18 male, I I female; mean age 57.9. L 13). The diagnosis was based on clinical symptoms, pulmonary function tests (PFT) values, and chest CT findings. All of the patients CT scans were obtained during suspended deep inspiration from the apices to the costophrenic angles. The mean lung attenuation (MLD) and parenchymal abnormalities related to emphysema were quantitatively calculated with tables, histograms and graphics at the whole lung. The lung density measurements revealed a mean density of -898.48 +/- 51.37 HU in patients with emphysema and -825.1 +/- 25.5 HU in control group. In addition, mean percentage of subthreshold attenuation values was found as 12.03 +/- 15.75 and 1.07 +/- 0.83 in patients with emphysema and control group, respectively. Compared with control group, the patients with emphysema had a significantly lower inspiratory MLD (p < 0.05). Additionally, statistically significant correlations were seen between the MLD and percentage of subthreshold values (r = 0.44, p < 0.05). In contrast, there was poor correlation between PFT measurements and the subthreshold values. In conclusion, pulmo-CT is a quick, simple method for quantitative confirmation of the presence of parenchymal abnormalities of lung as mosaic attenuation and should be used in combination with other radiological methods and PFT as it gives additional information to routine examinations in patients with emphysema.

Hypertrophic Pyloric Stenosis Mr Findings
(Modestum Ltd, 2006) Arslan, Halil; Bay, Ali; Temizoz, Osman; Etlik, Omer; Koseeoglu, Burhan; Kisli, Erol
Infantile hypertrophic pyloric stenosis (IHPS) is a condition affecting young infants, in which the antropyloric portion of the stomach becomes abnormally thickened and manifests as obstruction to gastric emptying. The clinical diagnosis hinges on palpation of the thickened pylorus, or "olive." Abdominal palpation is accurate but not always successful, in such cases, radiologic examinations including US or MRI can be performed. US is the first choice of imaging modality. Unfortunately, in case of difficulty by the sonographic diagnosis of IHPS such as overlying bowel gas, MRI could be useful for the diagnosis.
