Comparative Study
Relative value of MR imaging as compared with CT in the diagnosis of inflammatory paranasal sinus disease.
To evaluate the relative value of magnetic resonance (MR) imaging versus computed tomography (CT) in the diagnosis of inflammatory paranasal sinus disease. ⋯ CT is superior to MR imaging in the depiction of fine bony details and anatomic variants and thus is superior to MR imaging in helping plan functional endoscopic sinus surgery. However, there are patient groups in which MR imaging can be used as a primary tool in screening for sinusitis.

Clinical Trial
Malignant pleural effusions: treatment with small-bore-catheter thoracostomy and talc pleurodesis.
Thirty-two patients with a known primary malignancy and a symptomatic malignant pleural effusion underwent small-bore-catheter thoracostomy and talc pleurodesis. Twenty-three patients (72%) had a complete response; four (12%), a partial response; and five (16%), no response. ⋯ Complications included fever in 13 patients (41%) and moderate shortness of breath, chest pain, or both in six (19%). Small-bore-catheter thoracostomy and talc pleurodesis was successful in treating malignant pleural effusions.

To document abnormalities at computed tomography (CT) in adult survivors of acute respiratory distress syndrome (ARDS), to determine the relationships between CT patients during the acute phase and at follow-up, and to assess the effects of mechanical ventilation on the development of CT abnormalities. ⋯ A reticular pattern, with a striking anterior distribution, is a frequent finding of follow-up CT in ARDS survivors and is most strongly related to the duration of pressure-controlled inverse-ratio ventilation.

Comparative Study
Outpatient management of pneumothorax after fine-needle aspiration: economic advantages for the hospital and patient.
To evaluate the efficacy and cost savings of outpatient management of post-fine-needle aspiration (FNA) pneumothoraces with small-caliber catheters. ⋯ Outpatient management of simple pneumothoraces with placement of small-caliber catheters attached to one-way chest drain valves proved to be safe, efficient, and economical.

Comparative Study
Comparison of inversion-recovery gradient- and spin-echo and fast spin-echo techniques in the detection and characterization of liver lesions.
To compare respiratory-triggered inversion-recovery (IR) gradient- and spin-echo (GRASE) magnetic resonance (MR) imaging with respiratory-triggered T2-weighted fast spin-echo (SE) imaging in the diagnosis of liver metastases. ⋯ The respiratory-triggered IR GRASE sequence is a fast alternative to the respiratory-triggered fast SE sequence in the evaluation of suspected liver metastases.
