Selection of Tissue for Microscopic Study from Lungs Injected with Radio-opaque Material

Selection of tissue for microscopic study from lungs injected with radio-opaque material.

Choosing a suitable part of the lung by dissection distorts and often spoils the tissue for detailed histological study, especially when the peripheral part of the lung is concerned. These difficulties may be overcome by injecting the bronchial tree with radio-opaque material and choosing suitable areas from the abnormalities seen in a radiograph of the specimen. The parallax method is well sui...

Migration of radio-opaque markers injected into tendon grafts: a study using roentgen stereophotogrammetric analysis (RSA).

An increase in anterior laxity following reconstruction of the anterior cruciate ligament (ACL) can result from lengthening of the graft construct either at the sites of fixation and/or between the sites of fixation (i.e., graft substance). Roentgen stereophotogrammetric analysis (RSA), which requires that radio-opaque markers be attached to the graft, has been shown to be a useful technique in...

In vivo tissue compatibility of two radio-opaque polymeric biomaterials.

Polymeric biomaterials featuring intrinsic radio-opacity continue to attract considerable scientific attention. This work focusses on two polymers that contain covalently bound iodine, rendering the materials radio-opaque. The first material is hard, transparent and glass-like, and consists of methyl methacrylate, 2-(2'-iodobenzoyl)-ethyl methacrylate (1) and 2-hydroxyethyl methacrylate (HEMA),...

The fate of a radio-opaque medium injected into the sciatic nerve.

Considerable controversy exists concerning the relationship between the tissue spaces of the central nervous system and meninges, and those of the remainder of the body. It has been suggested that some materials may reach the central nervous system by routes other than through the hematoencephalic barrier. One suggested pathway is the tissue spaces of peripheral nerves. Other work in this labor...
