Diagnostic value of multiplanar CT reconstructions in the assessment of abdominal aortic aneurysms.

The increased use of ultrasonography and computed tomography result in the increased number of detected aneurysms, especially with relatively small diameters so the prevalence of the abdominal aortic aneurysms (AAA) is increasing. The aim of the study was to assess the usefulness of multiplanar (MPR) CT reconstructions in the evaluation of abdominal aortic aneurysms. Material comprises a group of 30 patients with the abdominal aortic aneurysm.

Abdominal aortic aneurysm in ultrasound and CT examination.

About 75% of AAAs are asymptomatic. They come to light as the chance findings of a lump with or without pulsation, noted on self-examination, a routine physical check-up, or during diagnostic investigations. Ultrasonography and CT are two most often used in diagnosing of AAAs.

Limitations in ultrasonographic evaluation of the abdominal aortic aneurysms.

The frequency of the abdominal aortic aneurysms (AAA) increases in older population, especially in men older than 50 years. In most cases the AAAs are revealed occasionally in routine ultrasound examination or in CT performed due to other reasons. The aim of the study was the assessment of the diagnostic value and limitations of ultrasound examination in the evaluation of the abdominal aortic aneurysms.

Typical findings for bronchiolitis in high resolution computed tomography.

High resolution computed tomography is a diagnostic modality of choice in imaging of interstitial lung diseases. HRCT enables visualization of the pathological findings invisible on plain radiographs and their evaluation at the level of the pulmonary lobule. The aim of the study was evaluation of typical HRCT findings in patients with bronchiolitis, and assessment of their usefulness in differential diagnosis.

High resolution computed tomography in sarcoidosis: typical findings.

Sarcoidosis is a systemic disorder of unknown cause in which noncaseating granulomas occur. Granulomas are formed in lymphatic or perilymphatic distribution, along lymphatics and in peribronchovascular interstitium. In some cases the granulomas are formed in interlobular septa or subpleural interstitium.

Morphological characteristics of malignant solitary pulmonary nodules.

The solitary pulmonary nodule is a common radiologic abnormality, which is often detected incidentally. It is defined as focal, round or oval areas of increased opacity in the lung which are caused by a variety of disorders, including neoplasm, infection, inflammations, and vascular and congenital abnormalities. Most of the solitary pulmonary nodules are benign, but up to 30%-40% of them are malignant.

High resolution computed tomography (HRCT) enables imaging of morphological changes invisible on plain chest radiograms or conventional CT. This is related to thin collimations of the scans and sharp (bone) algorithm of image reconstruction. In HRCT the lung interstitium may be evaluated at the level of the smallest functional unit, namely pulmonary lobule.

The value of ultrasound harmonic imaging in the diagnostics of the abdomen.

The tissue harmonic imaging (THI) is a new modality of ultrasonograph examination. The harmonic mode is characterized by a lower level of artifacts, due to reduction of side lobes energy and narrowed beam. The penetration in harmonic mode is also improved, so the visualization of deeper structures is often better.
