Noninvasive evaluation of the celiac trunk and superior mesenteric artery with multislice CT in patients with chronic mesenteric ischaemia.

2008

This study sought to assess the role of multislice computed tomography (MSCT) in patients with suspected chronic mesenteric ischaemia (CMI). Forty-five patients (29 men; mean age 68) underwent MSCT angiography of the abdomen for suspected CMI (main clinical finding: postprandial abdominal pain). The scan protocol was detectors/collimation 16/0.75 mm; feed 36 mm/s; rotation time 500 ms; increment 0.4 mm; 120-150 mAs and 120 kVp. A volume of 80 ml of contrast material was administered through an antecubital vein (rate 4 ml/s), followed by 40 ml of saline (rate 4 ml/s). Images were analysed on the workstation with different algorithms (axial image scrolling, multiplanar reconstructions, maximu…

Radioloģijas metožu pielietojums kriminālistikā

2022

Bakalaura darba tēma – “Radioloģijas metožu pielietojums kriminālistikā”. Tēmas aktualitāti nosaka tas, ka Latvijā vērojams otrs augstākais vardarbīgo nāves gadījumu skaits un visaugstākais slepkavības gadījumu skaits ES. Būtiski, ka aptuveni desmitajai daļai mirušo nāves cēlonis netiek noteikts, sestā daļa slepkavību netiek atklātas, augsta ir arī tiesu medicīnas ekspertu noslodze. Rodas jautājums, kā ir iespējams padarīt optimālāku tiesu medicīniskās izpētes un ekspertīžu veikšanu, un kā var paaugstināt to precizitāti, rezultativitāti. Darba mērķis - aprakstīt radioloģijas metodes kriminālistikā, izpētīt, kura no tām ir efektīvākā. Pētījuma jautājums: kura no radioloģijas metodēm krimināl…

Impact of intravascular enhancement, heart rate, and calcium score on diagnostic accuracy in multislice computed tomography coronary angiography.

2005

PURPOSE: To assess the effect of intravascular enhancement, heart rate, and calcium score on diagnostic accuracy in the detection of significant coronary artery stenosis using 16-row multislice computed tomography (MSCT). MATERIALS AND METHODS: One hundred patients (88 males; 59+/-11 years) with suspected coronary artery disease who had undergone conventional coronary angiography (CA) and MSCT-CA were retrospectively enrolled for the study. Patients underwent a MSCT-CA, with the following protocol: collimation 16x0.75 mm, gantry rotation time 420 ms, feed/rotation 2.8 mm, kV 120, mAs 400-500. The protocol for contrast material administration was 100 ml of Iodixanol 320 mgI/ml at 4 ml/s and …

Preprocessing methods for nodule detection in lung CT

2005

Abstract The use of automatic systems in the analysis of medical images has proven to be very useful to radiologists, especially in the framework of screening programs, in which radiologists make their first diagnosis on the basis of images only, most of those corresponding to healthy patients, and have to distinguish pathological findings from non-pathological ones at an early stage. In particular, we are developing preprocessing methods to be applied for pulmonary nodule Computer Aided Detection in low-dose lung Multi Slice CT (computed tomography) images.
