#1 Sta je bolje MRI ili CTI -sken
Moze li neko da mi pomogne u trazenju klinike( moze i privatna ) sa dobrim doktorom ?

CT se zasniva na rendgenskom zracenju, te stoga i sadrzi odredjene rizike po zdravlje, dok do sada nije pronadjena eventualna stetnost MRI-a (koji koristi jako magnetno polje za pozicioniranje i registraciju vodikovih atoma u tijelu) na pacijenta.

ovdje kaze-ako je u pitanju skeniranje sa vecim kontrastom(npr.kosti-okolo meko tkivo) CT,ako je samo meko tkivo MRI.CT je i zracenje,MRI to nije.CT je jeftiniji i brzi,MRI skuplji.
prepusti taj zbor doktoru.
a nadam se da ce ti neko pomoci i preporuciti dobrog doktora.
MRI versus CT
A computed tomography (CT) scanner uses X-rays, a type of ionizing radiation, to acquire its images, making it a good tool for examining tissue composed of elements of a higher atomic number than the tissue surrounding them, such as bone and calcifications (calcium based) within the body (carbon based flesh), or of structures (vessels, bowel). MRI, on the other hand, uses non-ionizing radio frequency (RF) signals to acquire its images and is best suited for non-calcified tissue, though MR images can also be acquired from bones and teeth[28] as well as fossils.[29]
CT may be enhanced by use of contrast agents containing elements of a higher atomic number than the surrounding flesh such as iodine or barium. Contrast agents for MRI are those which have paramagnetic properties, e.g. gadolinium and manganese.
Both CT and MRI scanners can generate multiple two-dimensional cross-sections (slices) of tissue and three-dimensional reconstructions. Unlike CT, which uses only X-ray attenuation to generate image contrast, MRI has a long list of properties that may be used to generate image contrast. By variation of scanning parameters, tissue contrast can be altered and enhanced in various ways to detect different features. (See Applications above.)
MRI can generate cross-sectional images in any plane (including oblique planes). In the past, CT was limited to acquiring images in the axial (or near axial) plane. The scans used to be called Computed Axial Tomography scans (CAT scans). However, the development of multi-detector CT scanners with near-isotropic resolution, allows the CT scanner to produce data that can be retrospectively reconstructed in any plane with minimal loss of image quality.
For purposes of tumor detection and identification in the brain, MRI is generally superior.[30][31][32] However, in the case of solid tumors of the abdomen and chest, CT is often preferred due to less motion artifact. Furthermore, CT usually is more widely available, faster, much less expensive, and may be less likely to require the person to be sedated or anesthetized.
MRI is also best suited for cases when a patient is to undergo the exam several times successively in the short term, because, unlike CT, it does not expose the patient to the hazards of ionizing radiation.

Sto se tice MRI-ja nakon klinickog centra najkvalitetniji aparat (1,5 T) ima poliklinika Sunce...
Ima MRI na jos par mjesta ali snimak nije kvalitetan (aparati su kod privatnika ugl 0,5 T)

Hvala ti za ovu informaciju to mi je trebalo. Znaci pare koje sam dala na klinici Rezonansa kod Gorana Sulejmanpasica su donekle bacene pare.zelenooka blogerica wrote:Sto se tice MRI-ja nakon klinickog centra najkvalitetniji aparat (1,5 T) ima poliklinika Sunce...

MRI Tuzla. Bar je prije 2 godine bio najjaci. Jbg. meni nisu nista našli.

Ne bi ja tako daleko isla da si bacila pare. Sunce ima najnoviju tehnologiju - to da...rajvosa 69 wrote:Hvala ti za ovu informaciju to mi je trebalo.

Ali kad govoris o dr. - Goran pa 10 mjesta pa ostali. Mislim da je bitno i ko taj MRI snimak gleda. Kod Gorana su novi aparati, nekih 2 god. od kako je otvorio ordinaciju. E sad, ako nemas povjerenja u njega...
