Venous plethysmography values in patients with spinal cord injury.

To determine whether venous hemodynamics differ fundamentally between patients with spinal cord injury (SCI) and the abled-bodied population, quantitation of lower extremity venous plethysmography values was performed in 14 SCI patients and ten able-bodied subjects. The control group had an average maximum venous outflow (MVO) of 59.3 +/- 2.75 mL/min/100mL of tissue, mean +/- SE, and an average venous capacitance (VC) of 3.2 +/- 0.13mL/100mL. In contrast, the SCI patients had an average MVO of 32.5 +/- 2.57mL/min/100mL and an average VC of 2.3 +/- 0.17mL/100mL. The differences between the two groups were statistically significant, suggesting that the standard venous function index of plethysmography values used in the general population may not be applicable to the SCI population and that, therefore, a new standard for SCI patients derived from a larger data base should be sought.

MR pyelography in the assessment of hydroureteronephrosis: single-shot thick-slab RARE versus multislice HASTE sequences.

BACKGROUND: We used magnetic resonance (MR) pyelography to compare the value of thick-slab single-shot rapid acquisition with relaxation enhancement (RARE) sequence with that of multislice half-Fourier acquisition single-shot turbo-spin-echo (HASTE) sequence in evaluating the full spectrum of morphologic features in a group of patients with hydronephrosis. METHODS: MR pyelographic images, with the use of thick-slab RARE and multislice HASTE sequences in 90 patients, were evaluated for image quality, presence of hydronephrosis, and level and cause of obstruction. RESULTS: HASTE sequences provided images of better quality than did RARE sequences (p < 0.001). There was no statistically significant difference in demonstrating the presence of hydronephrosis (p = 0.5) and level of obstruction (p = 0.125). Sensitivity, specificity, and accuracy in diagnosing cause of obstruction were 61.7%, 62.5%, and 62%, respectively, for RARE sequences and 80%, 82.5%, and 81%, respectively, for HASTE sequences, with a statistically significant difference (all p < 0.05). CONCLUSION: Multislice HASTE sequence provides better diagnostic information than does thick-slab RARE sequence, particularly in evaluating the cause of obstruction.

Gallbladder duplication: MR cholangiography demonstration.

Gallbladder duplication is a rare anatomic malformation. We present a case of gallbladder duplication in a patient who underwent laparoscopic cholecystectomy in which breath-hold magnetic resonance cholangiography showed the biliary anomaly, allowing a correct preoperative differentiation of the specific type of duplication.

Mucinous cystadenocarcinoma of the lung: CT-pathologic correlation in three cases.

Mucinous cystadenocarcinoma (MCA) is a rare tumor that is considered to be a cystic variant of mucin-producing lung adenocarcinoma. MCA expands grossly by storing mucus and contains few neoplastic cells. We present the CT images of three patients with MCA and correlate them with pathologic specimens. The CT findings of MCA include a uniform low-attenuation, focal thickening of the cystic wall and enhancing septa.

Diagnostic pitfalls of breath-hold MR urography in obstructive uropathy.

Breath-hold MR urography (MRU) is being used with increasing frequency to evaluate urinary tract pathology. Although multiple studies have documented the accuracy of breath-hold MRU in the evaluation of obstructive uropathy, pitfalls associated with this technique may result in diagnostic errors. This essay illustrates both technical and interpretive pitfalls of MRU and suggests strategies for their recognition and avoidance.

MR white lung sign: incidence and significance in pulmonary consolidations.

PURPOSE: The presence of a pulmonary consolidation with a signal intensity comparable with that of the static fluid on heavily T2-weighted MR images has been named the "MR white lung sign." This sign has been described in mucinous bronchioloalveolar carcinoma (BAC). Our purpose was to establish the frequency and significance of this sign in pulmonary consolidations of varied causes. METHOD: In this prospective study, 83 patients with pulmonary consolidation underwent MR examination between January and December 1999. Segmental or lobar consolidations were due to pneumonia without central obstruction (n = 22), pneumonitis with central obstruction (n = 21), cicatricial atelectasis (n = 8), passive atelectasis (n = 10), radiation pneumonitis (n = 8), mucinous BAC (n = 5), infarction (n = 3), bronchiolitis obliterans organizing pneumonia (n = 3), nonmucinous BAC (n = 2), and lymphoma (n = 1). The MR white lung sign was considered present when the signal intensity of a pulmonary consolidation was comparable with that of the static fluid on heavily T2-weighted images obtained with MR hydrography sequences. Interobserver agreement, sensitivity, and specificity of the white lung sign in diagnosing mucinous BAC were calculated. RESULTS: The MR white lung sign was present in 7 (8%) of 83 consolidations, including 5 (100%) of 5 cases of mucinous BAC and 2 (10%) of 21 cases of obstructive pneumonitis. The frequency of the white lung sign was 100% in mucinous BAC and 2.6% in consolidations due to other causes. The difference was statistically significant (p < 0.05). CONCLUSION: The white lung sign is an uncommon finding in pulmonary consolidations evaluated with heavily T2-weighted sequences. However, the sign is characteristic of mucinous BAC and adds specificity to the radiologic diagnosis.

[Computed tomography in endobronchial mucus accumulation].

To investigate the value of CT in depicting endobronchial mucoid collections, the authors retrospectively reviewed the CT scans of 22 patients, 14 with mucous plugs, 7 with mucoid pseudotumors, and one with a bronchocele due to bronchial atresia. Atelectasis could be seen in 11 of 14 patients with mucous plugs. In 12 of 14 patients with mucous plugs CT showed the involved bronchi filled by fluid representing abnormal mucus accumulation. In the patients with atelectasis CT showed mucus-filled bronchi as low-attenuation branching structures (mucoid bronchogram). All the mucoid pseudotumors appeared as low-attenuation (< 20 HU) polypoid wall lesions with no involvement of the bronchial walls. In a patient with bronchial atresia CT showed a solitary pulmonary nodule (representing the obstructed and dilated bronchus filled by mucus) surrounded by peripheral pulmonary hyperinflation. Characteristically, the endobronchial mucoid collections never enhanced after bolus contrast medium. Endobronchial mucoid collections had to be differentiated from endobronchial neoplasms. In some cases bronchoscopy was necessary to make the differential diagnosis. In conclusion, CT is a valuable tool with good sensitivity and specificity in diagnosing endobronchial mucoid collections.
