A Mammogram And Breast Ultrasound-Based Expert System With Image Processing Features For Breast Diseases [ RC280.B8 U51 2007 f rb ].

Barah payu dara adalah penyakit yang paling banyak meragut nyawa kaum hawa. Kadar sembuh dari penyakit ini boleh ditingkaykan jika ia dapat dikesan secara awal. Pengesahan awal penyakit ini dapat dilakukan melalui ujian mamografi yang terbukti keberkesanannya. Survival rates for breast cancer patients may be increased when the disease is detected in its earliest stage through mammography. A thorough assessment during breast screening would also include clinical, physical examination and ultrasound. The implementation of mass screening would result in increased caseloads for radiologists which would incur chances of improper diagnosis

Pseudocolouring Enhancement Processing Of Ovarian Ultrasound Images.

Image processing may be employed on ovarian ultrasound images to assist doctors in diagnostic analysis

Ovaidan Ultrasound Image Enhancement By Pseudocolouring.

Image processing may be employed on ovarian ultrasound images to assist doctors in diagnostic analysis. The gray levels of ovarian images are usually concentrated at the zero end of the spectrum ,making the image too low in contrast and too dark for the naked eye. This paper examines the effectiveness in displaying gray level ultrasound images as colour images and proposes a pseudocolouring approach for enhancing features in ultrasound ovarian image, which allows easy discrimination Of texture information

Automated Seed-Based Region Growing Using The Moving K-Means Clustering For The Detection Of Mammographic Microcalcifications.

Mammography is by far the proven method of early detection of breast cancer. However, mammography is not without its problems. It is amongst the most difficult of radiological images to interpret as the images are of low contrast and features indicative of abnormalities are very subtle and minute. In this study, a new method of automated edge detection technique is proposed to detect the abnormalities in a region of interest in a mammogram

Unprocessed mammograms and ultrasound images are sometimes difficult to assess through the naked eye. Images that are inflicted with degradations due to overexposure. inadequate lighting or faulty electronic imaging equipment can be rendered useful through the process of image restoration. Degradations such as defocus or various types of noises can be removed and thus made more suitable for interpretations in the medical field. For this purpose, a software package named Image Restoration 2 (IR2) was developed

Frontal mucocele masked as upper lid abcess-a case report

Frontal mucocele is not commonly masked as upper lid abscess.A 72-year-old Chinese man with underlying hyperthyroidism complained of left upper eyelid swelling of 6 months duration. The swelling had persisted and worsen when intravenous antibiotic was changed oral type. Visual acuity on presentation was hand motion and reverse relative afferent pupillary defect was present. Because the swelling was large and resulted in mechanical ptosis and ophthalmoplegia, a CT imaging was performed, which showed huge left frontal mucocele eroding the supereromedial orbital rim. The left globe was displaced inferolaterally but there was no extension into brain parenchyma. Fundus examination showed pale optic disc with dull macula. Old laser marks were seen at peripheral fundus. Referral to ortholaryngologist was made and endoscopic sinus surgery and evacuation of mucopyocoele was done. Culture and sensitivity of the fluid showed no organism. He recovered well postoperatively with additional two weeks of antibiotics. We highlight the necessity of surgical drainage of mucocele, following a course of antibiotic

Severe endogenous endophthalmitis with panophthalmitis-lessons to learn

Endogenous endophthalmitis is a devastating intraocular infection. Finding the primary infection and directed treatment is life-saving. We describe a 47-year-old man, with uncontrolled diabetes mellitus, who presented with two weeks history of progressive reduced vision and redness of the left eye (LE). He was generally unwell since a month, previously. Examination showed relative afferent pupillary defect (RAPD) in the affected eye and visual acuity was hand movement. There was moderate anterior chamber and vitreous reaction. Fundus examination showed a huge dome-shaped choroidal mass covering the entire macula. Diagnosis of severe endogenous endophthalmitis was made, with isolation of Enterobacter sp. from his blood culture. Meanwhile, he also had elevated inflammatory markers with presence of leucocytosis, neutrophilia and elevated erythrocyte sedimentation rate (ESR) as well as C-reactive protein (CRP). Vitreous tap and aqueous tap had no growth, He improved with combination of intravitreal and systemic antibiotic, as shown by the resolved fever and reduced inflammatory markers but progressive inflammation occluded the fundus details and the LE vision eventually became no projection of light despite treatment. Subsequently, he developed rubeotic glaucoma and was treated conservatively because the LE was painless with poor vision. The repeated blood culture and urine was normal. In conclusion, endogenous endophthalmitis with eventual panophthalmitis is difficult to treat and has very poor visual prognosis. Our case highlights the challenges faced in the management of vision-threatening endophthalmitis and panophthalmitis in this patient
