Definitions
- Magnetic Resonance Imaging (MRI) scanning is a method of imagmglfTe "" human body or other fleshy objects e.g. animals, either alive or dead. It depends on the object being placed in a large and uniform magnetic field (commonly ranging from 0.2-7.0 Tesla field strength according to the particular machine used).
- the image is created by disturbance of molecules of the body by radiofrequency (RF) pulses causing resonance of these molecules. After the RF pulse, the molecules realign with the magnetic field and in so doing, emit a weak RF signal of their own. This signal is detected and analysed by a computer and a signal map created of the interrogated body part such that a grayscale image is displayed.
- RF radiofrequency
- the appearance is usuaUy that of 'sHces' throught he body revealing the inner organs. It is useful in medical practise, to place needles in these inner organs in the presence of disease, both to extract tissue and fluid samples for analysis (biopsy) or to pass fluids or instruments down the needles to alter the tissue of interest in a variety of pre ⁇ specified ways.
- the precise position of the needle tip is clearly vital for accurate diagnosis and/or therapy in this context.
- the needle To use a needle in an MRI scanner, the needle must fulfil all the requirements for a medicinal needle in terms of strength and body compatibility as well as being compatible with the MRI imaging apparatus in that it must be both clearly visible when scanned as well as causing no distortion artefact to the final image. Any magnetic object will distort the magnetic field and thus the image, making accurate placement difficult.
- Such needles as are used currently, are made of metal alloys with high non-ferrous metal content and a low relative proportion of Iron but these still cause significant artefact especially at the needle tip-the most important part.
- the needle is manufactured out of non-metallic materials such as carbon fibre, glass fibre, plastics or ceramics so as to cause no artefact on MRI scanning and allow non-distorted tip visualisation.
- the needle is made of fibre composite materials such as carbon or glass fibre wherein the fibres are arranged either axially, spirally, in circular fashion or in a combination of these orientations
- the needle is sterilizable by heat, chemicals and/or irradiation techniques allowing re-use of the needle.
- Figure 1 shows the side view of the needle and a selection of accompanying components.
- FIG. 1 shows the needle end-on
- the needle comprises an outer cylindrical tube 1 of carbon fibre, glass fibre, plastic or ceramic material with length and wall dimensions 5 and 6 variable according to the task required i.e.large or small needles.
- the needle has a connector 2 attached to its proximal end to allow the connection of omer apparatus.
- the needle bore 5 allows passage of fluids in ei ⁇ ier direction, the insertion of an obturator, mandril or trocar 3 , as well as the passage of implements such as optical light fibres 4 , catheters and more complex instruments such as ultrasound probes
- the needle and trocar assembly can be adapted to perform core biopsies of tissues as is currendy undertaken with metallic needles.
- the carbon fibre tubing is manufactured either by 'pultrusion' of the fibres over a mandril with the fibres arranged both axially and spirally, or wrapping preformed carbon fibre sheeting around a mandril with subsequent polishing of the surfaces.
