From March 1944, north-western France became the focal point for air activity, the largest sustained air offensive of the war, codenamed the Transportation Plan.
However, primary pulmonary lymphoma may manifest as focal areas of air space opacification on CT and this can vary markedly in size from subsegmental to confluent involvement of an entire lobe.
CT findings in perforation include pneumoperitoneum, abscess or focal collection of air or fluid with phlegmonous changes adjacent to the perforation site and leakage of oral contrast (Fig. 11).
The schematic setup of the model eye is depicted in Fig. 2. The femtosecond laser pulses from the AOFL instrument are focused into a water chamber by an achromatic lens with 45 mm focal length in air which models the cumulative refractive power of the cornea and crystalline lens of the human eye.
Dallas Fort Worth, Houston, and San Antonio are focal points for civilian air transportation.
At all wavelengths used, the laser fluence at the ultrasound focal location, measured in air was <20 mJ/cm.
The severity of histologic lesions was assed using a score (HIS) that was based on six parameters: intra-alveolar edema, hyaline membrane formation, hemorrhage, recruitment of granulocytes into the air space, focal alveolar collapse or consolidation, and epithelial desquamation/necrosis of airways or alveoli.
Diagnostic signs for VPGI on CT include the presence of local fluid, perigraft retention, pseudoaneurysm formation, and focal bowel thickening and air bubbles [ 6], though these findings are present in just 50% of VPGI cases and are even considered normal findings in the early postoperative period.
Note that tracking the focal position of the air-solution interface during drying is fundamental to measuring the correct reflectivity values.
