Background The traumatic or degenerative internal derangement of the knee requires certain investigations for the establishment of diagnosis, in addition to clinical history and a thorough physical examination. The use of arthrography and arthroscopy improves the accuracy of the diagnosis. MRI scanning of the knee joint has often been regarded as the noninvasive alternative to diagnostic arthroscopy. Objective The purpose of the study was to correlate clinical and low field MRI findings with arthroscopy in internal derangement of the knee. Methods Forty one patients with suspected internal derangement of the knee were subjected to MR examination followed by arthroscopy. Clinical criteria used were history, mode of injury, Mc Murray’s, Apley’s grinding, Thessaly’s test for meniscal injury. Drawer test was considered to be essential for clinical diagnosis of cruciate ligament injury. MRI of the knee was performed in low field open magnet (0.35T, Magnetom C, Seimens). Arthroscopy was done within two months of MR examination and was considered gold standard for the internal derangement of the knee. Results The sensitivity, specificity, diagnostic accuracy of clinical examination were 96.1%, 33.3% and 73.1% respectively for medial meniscal tear; 38.4%, 96.4% and 78.1% respectively for lateral meniscal tear. The sensitivity, specificity, diagnostic accuracy of MRI were 92.3%,100% and 95.1% for medial meniscal tear; 84.6%96.4% and 92.6% respectively for lateral meniscal tear. ConclusionClinical examination showed higher sensitivity for medial meniscal tear compared to MRI, however with low specificity and diagnostic accuracy. Low field MRI showed high sensitivity, specificity, diagnostic accuracy for meniscal and cruciate ligament injury, in addition to associated derangement like articular cartilage damage, synovial thickening.DOI: http://dx.doi.org/10.3126/kumj.v9i3.6300 Kathmandu Univ Med J 2011;9(3):174-8

Background Patient acceptance is an important factor when implementing imaging methods in clinical practice in line with availability, diagnostic accuracy, and cost-effectiveness. Purpose To investigate patient experience and acceptance regarding18F-sodium fluoride (NaF) positron emission tomography/computed tomography (PET/CT), 11 C-choline-PET/CT, whole-body magnetic resonance imaging (WB-MRI), and 99mTc-hydroxymethane diphosphonate (HDP) single photon emission/computed tomography (SPECT/CT). Material and Methods One hundred and forty-nine patients with prostate cancer filled in a questionnaire regarding their experience of the imaging procedures they had been undergoing as part of a diagnostic accuracy study. Each patient had been undergoing a NaF-PET/CT, a WB-MRI, and either a SPECT/CT (group A) or a choline-PET/CT (group B). Results All four imaging methods received overall experience ratings at the favorable end of a 5-point Likert scale with the two PET/CT scans receiving marginally better average ratings (2.0) compared to SPECT/CT (2.2) and WB-MRI (2.3). The arm positioning above the head was the most uncomfortable part of the three nuclear medicine scans, whereas the acoustic noise was the most unpleasant part of the WB-MRI. The experience of staff instruction was relatively strongly correlated to the overall scanning experience of all four imaging modalities. Overall, the patients were willing to repeat the four imaging methods and NaF-PET/CT was the method most preferred in both groups. Conclusion Four imaging procedures were evaluated from the perspective of a selected group of prostate cancer patients. NaF-PET/CT, choline-PET/CT, WB-MRI, and bone SPECT/CT are well accepted imaging methods, and most patients prefer NaF-PET/CT.

Entrapment Syndromes

Chapter 106 discusses the normal MRI anatomy and imaging findings of the major and common disorders leading to internal derangements of the wrist and hand including osteonecrosis (ON) of the scaphoid and lunate bones, tendon and ligamentous injuries, and common nerve entrapment syndromes. The anatomy of the wrist and hand is complex. A wide spectrum of traumatic, inflammatory, and degenerative conditions affects the wrist and hand. High-resolution MRI of the wrist and hand and MRA of the wrist provide excellent evaluation of the osseous and soft tissue structures and in many instances represent the study of choice. Radiography, CT, arthrography, CTA, and diagnostic US represent the alternative and/or complementary imaging methods in the evaluation of these structures.

Purpose This study provided reference data and examined psychometric properties for clausal density (CD; i.e., number of clauses per utterance) in children between ages 4 and 9 years from the database of the Edmonton Narrative Norms Instrument (ENNI). Method Participants in the ENNI database included 300 children with typical language (TL) and 77 children with language impairment (LI) between the ages of 4;0 (years;months) and 9;11. Narrative samples were collected using a story generation task, in which children were asked to tell stories based on six picture sequences. CD was computed from the narrative samples. The split-half reliability, concurrent criterion validity, and diagnostic accuracy were evaluated for CD by age. Results CD scores increased significantly between ages 4 and 9 years in children with TL and those with LI. Children with TL produced higher CD scores than those with LI at each age level. In addition, the correlation coefficients for the split-half reliability and concurrent criterion validity of CD scores were all significant at each age level, with the magnitude ranging from small to large. The diagnostic accuracy of CD scores, as revealed by sensitivity, specificity, and likelihood ratios, was poor. Conclusions The finding on diagnostic accuracy did not support the use of CD for identifying children with LI between ages 4 and 9 years. However, given the attested reliability and validity for CD, reference data of CD from the ENNI database can be used for evaluating children's difficulties with complex syntax and monitoring their change over time.
