A 1-year-old male canary (Serinus canaria, Jibber breed), with a protuberance on the left tibia was referred to the clinic. The bird was not able to use the affected foot to stand on its perch. Results of radiographs revealed a radio-opaque hard tissue mass. The canary was euthanatized and submitted for necropsy. On histopathologic examination, the mass was diagnosed as an ossifying fibroma tum...

In an attempt to learn more about the physiologic changes in the cardiovascular system during angiocardiography and the nature of mixing of radio-opaque dyes with blood, radiopotassium and Diodrast I' dilution curves were obtained before and during angiocardiography. Studies in patients without valvular disease and with mitral valvular disease indicated an increased cardiac output during angioc...

The recessive opaque-2 mutant gene (o2) reduces α-zeins accumulation in maize endosperm, changes the amino acid composition of maize kernels, induces an opaque endosperm, and increases the lysine content of kernels. The quality protein maize (QPM) inbred line CA339 (o2o2) and an elite normal inbred line liao2345 (O2O2) were used to construct o2 near-isogenic lines (NILs) by marker-assisted sele...

A 40-year-old female presented with a 10 year history of left sided facial pain and occasional purulent nasal discharge, refractory to antibiotics. Dental examination showed 3 missing teeth in left maxilla one of which had no history of extraction. X-ray paranasal sinus showed a bony opacity in the maxillary sinus but nasal endoscopy was normal. C.T. scan revealed a radio-opaque shadow arising ...

The complications caused by iatrogenic foreign bodies are well known, but cases are rarely published because of the medico-legal implications.1 Early identification of a foreign body can prevent hazardous and detrimental complications. Medical practitioners may occasionally be misled by overlapping images of radio-opaque objects on X-rays and misinterpret these as foreign bodies. We present a c...

A 35-year-old man presented with persistent pain in right iliac fossa and nausea for one month. He did not have vomiting or urinary symptoms and had normal bowel habits. Physical examination revealed minimal tenderness in right iliac fossa. Microscopic urine analysis, complete blood count, and stool examinationwere within normal limits. Computed tomographic (CT) scan showed diffuse, eccentric w...

Lanthanum carbonate (LC) is used as a phosphate binder in dialysed patients. Abdominal pain and constipation are known side effects of its use. Furthermore, in radiological studies, LC tablets are seen as intense radio-opaque deposits within the entire gastrointestinal tract-findings which can lead to diagnostic misinterpretations. An elderly patient on peritoneal dialysis and taking LC present...

PURPOSE To evaluate Lipiodol as a liquid, radio-opaque fiducial marker for image-guided radiation therapy (IGRT) for bladder cancer. MATERIALS AND METHODS Between 2011 and 2012, 5 clinical T2a-T3b N0 M0 stage II-III bladder cancer patients were treated with maximal transurethral resection of a bladder tumor (TURBT) and image-guided radiation therapy (IGRT) to 64.8 Gy in 36 fractions ± concurr...
