To evaluate the presence of subpleural sparing as an aid in differentiation of contusion from other causes of lung opacification in children. ⋯ The presence of subpleural sparing on CT scans enables accurate identification of lung contusion and differentiation of contusion from other causes of lung opacification in children after trauma.

T2-weighted spin-echo (SE) magnetic resonance imaging in the liver was compared with four sequences: fast and conventional half-Fourier single-shot turbo SE (HASTE) and breath-hold and respiratory-triggered turbo SE. ⋯ Images obtained with the fast HASTE sequence were free from motion artifacts, and observer diagnostic performance was similar to that with the respiratory-triggered turbo SE sequence.

To design a decision tree according to time from irradiation and site, morphology, and number of microcalcifications for the rational treatment of patients with microcalcifications at the lumpectomy site after breast-conserving therapy (BCT), to minimize performance of biopsy. ⋯ Follow-up mammography is an option when benign-appearing microcalcifications develop at the lumpectomy site depending on time of appearance and number; it is the primary recommendation when these microcalcifications develop within 3 years after treatment.

To evaluate the technique used for and long-term results of percutaneous cecostomy tube placement for the treatment of fecal incontinence in children. ⋯ Percutaneous cecostomy and antegrade enemas are very successful in achieving fecal continence and patient independence and acceptability, with minimal early and late complications.

Comparative Study
Patients with emphysema: quantitative CT analysis before and after lung volume reduction surgery. Work in progress.
To quantitatively assess the morphologic changes in the lungs after lung volume reduction surgery and determine whether changes at quantitative computed tomography (CT) reflect changes in lung function. ⋯ Substantial decreases in the lung volumes and emphysema index, increased airflow, possible reexpansion of some remaining lung, and the relation between preoperative quantitative CT indexes and clinical outcome suggest a multifactorial mechanism for improvement seen after surgery.
