Abstract
Since the establishment of the Korean Society of Nuclear Medicine (KSNM) in 1961 by Professor Munho Lee, the KSNM has been progressing in various medical fields. Many papers have been published in the Korean Journal of Nuclear Medicine (KJNM), the official journal of KSNM, since 1967 and other domestic/international journals. Here, we tried to highlight the academic activities of KSNM members from the perspective of general nuclear medicine. After the introduction of the 99Mo/99mTc generator, general nuclear medicine has widened the field of clinical application with the advancement of imaging technology and emerging new radiopharmaceuticals; however, there have been many ups and downs. Treatment, as well as diagnosis, was a major concern in Korean nuclear medicine. With the recent advent of single-photon emission computed tomography/computed tomography, we hope that our old dream (diagnosis and treatment under the same principle of nuclear medicine) comes true.

Abstract
OBJECTIVE: To assess the role of single photon emission computed tomography (SPECT/CT) in the evaluation of knee pain as well as comparing bone scintigraphy (BS), SPECT and SPECT/CT, and assessing the incremental value of SPECT/CT. METHODS: BS, SPECT and SPECT/CT of patients with knee pain (39 patients, 65 knees, 105 lesions) were directly compared for lesion detection, localisation and characterisation using lesion-based, knee-based and patient-based analyses in this retrospective study. RESULTS: Lesion detection: BS (91.4%), SPECT (100%) and SPECT/CT (100%). SPECT and SPECT/CT detected significantly more lesions than BS (p < 0.05). Lesion localisation: BS (38.5-41.7%), SPECT (74.4-83.3%) and SPECT/CT (100%). SPECT localised significantly more lesions than BS; SPECT/CT localised significantly more lesions than BS and SPECT (p < 0.01). Lesion characterisation: BS (23.0-52.1%), SPECT (30.8-56.2%) and SPECT/CT (92.3-96.9%). SPECT/CT characterised significantly more lesions than BS and SPECT (p < 0.01). Characterisation of non-arthropathy lesions: BS (6.25%), SPECT (12.5%) and SPECT/CT (93.75%). SPECT/CT characterised significantly more non-arthropathy lesions than BS and SPECT (p < 0.01). BS and SPECT detected none, while SPECT/CT detected 100% of the causative/contributing/associated conditions that co-existed with osteoarthritis. Therefore SPECT/CT detected not only just osteoarthritis but also the causative/contributing/associated conditions. CONCLUSION: SPECT/CT added significant incremental value to BS and SPECT irrespective of whether evaluation was lesion-based, knee-based or patient-based. SPECT/CT represents a viable alternative to MRI, and addition of SPECT/CT to BS and SPECT should be considered in the evaluation of knee pain. ADVANCES IN KNOWLEDGE: Incremental value of bone SPECT/CT in knee pain.

Abstract
Background The aim of this study was to investigate bone mineral density (BMD) and the biomechanical and histological effects of posterior cruciate ligament (PCL) rupture on the lateral femoral condyle. Material/Methods Strain on different parts of the lateral femoral condyle from specimens of normal adult knee joints, including 12 intact PCLs, 6 ruptures of the anterolateral bundle, 6 ruptures of the postmedial bundle, and 12 complete ruptures, was tested when loaded with different loads on the knee at various flexion angles. Lateral femoral condyles were also collected randomly from both the experimental side in which the PCLs were transected and the control side from 4 sets of 12 matched-mode pairs of rabbits at 4, 8, 16, and 24 weeks after surgery, and their BMD and morphological and histological changes were observed. Results Partial and complete rupture of the PCL may cause an abnormal load on all parts of the lateral femoral condyle with any axial loading at all positions. Noticeable time-dependent degenerative histological changes of the lateral femoral condyle were observed in the rabbit model of PCL rupture. All of the PCL rupture groups had a higher expression of matrix metalloproteinase-7 (MMP-7) and collagen type II than the control group at all time points (P<0.05), but no significant difference in BMD (P>0.05). Conclusions Rupture of the PCL may trigger a coordinated response of lateral femoral condyle degeneration in a time-dependent manner, to which the high level of expression of MMP-7 and collagen type II could contribute.

Abstract
BACKGROUND We analyzed the histopathologic findings in end-stage osteoarthritic ankle joint tissue that display increased uptake of bone-seeking radiotracer in single-photon emission computed tomography-computed tomography (SPECT-CT) imaging. METHODS Six consecutive patients with end-stage osteoarthritis undergoing total ankle replacement received preoperative SPECT-CT imaging using (99m)Technetium dicarboxypropane diphosphonate ((99m)Tc-DPD). Using imaging data for stratification, osteochondral tissue sections were prepared from SPECT-positive (+) and -negative (-) areas of tibial and talar resection specimens. Histomorphometric analyses of osteoblast numbers, collagen deposition, and cartilage degeneration were performed on hematoxylin and eosin, van Gieson's and Safranin-O stained tissue sections. Osteoclast activity was visualized using tartrate-resistant acid phosphatase (TRAP) staining. RESULTS Increased (99m)Tc-DPD uptake was observed exclusively subjacent to the subchondral bone plate of tibial and talar joint compartments. SPECT(-) tissues displayed typical fatty marrow morphology containing mainly collagen-positive blood vessels and few marrow and bone-lining cells. SPECT(+) tissues were characterized by increased numbers of active bone-lining osteoblasts depositing collagen fibers. Collagen area fraction of subchondral bone marrow was significantly increased in SPECT(+) (0.52 ± 0.21) compared with SPECT(-) (0.29 ± 0.13) tissues (P = .30). Multinucleated TRAP(+) osteoclasts were absent from bone formation sites, but associated with vascular structures invading articular cartilage through the subchondral bone plate. Increased (99m)Tc-DPD uptake was specifically and strongly correlated with increased osteoblast numbers (P = .011), and with collagen area fraction (P = .030) but not with Mankin score (P = .202), or with osteoclast number (P = .576). CONCLUSION Subchondral bone tissues in SPECT(+) areas of end-stage ankle osteoarthritis were histologically characterized by increased osteoblast-mediated bone formation in the absence of functional osteoclasts, and increased cellularity and collagen deposition in marrow tissues. CLINICAL SIGNIFICANCE Our findings suggest a pathologic bone-remodeling process in end-stage ankle OA areas with increased (99m)Tc-DPD uptake.

Abstract
OBJECTIVE Destructive techniques such as histology and biochemical assays are still regarded the gold standard to study the effects of novel therapies or etiologic aspects of osteoarthritis in small animal models. These techniques are time-consuming and require many animals. Multi-pinhole single photon emission computed tomography (MPH-SPECT) is a relatively novel, high resolution imaging technique which enables assessment of biological processes in real-time and thus it might provide a good substitute for destructive assessment techniques. DESIGN For this study, we assessed mono-iodoacetate (MIA) induced osteoarthritic knees in 18 rats. The animals were scanned using MPH-SPECT/CT and a diphosphonate labelled with 99m-technetium as the radioactive tracer to monitor subchondral bone turnover (bone-scan) at 2 (n = 18), 14 (n = 12) and 42 (n = 6) days after injection of MIA. At each time-point six animals were sacrificed and also assessed with high-resolution micro-computed tomography (μCT) and histology. RESULTS At 2 days after injection of MIA, the MPH-SPECT/CT already showed elevated bone turnover in the affected knee, whereas with histology and μCT we could not detect clear alterations at all this time-point. The increase in bone turnover induced by MIA was elevated further at 14 and 42 days after injection. At this time alterations on histology and μCT scanning also became visible. CONCLUSIONS MPH-SPECT/CT proved to be a highly sensitive assessment technique for experimental osteoarthritis in small animal models, detecting real-time changes in bone turnover at a very early time point, which might make it a valuable technique to measure the direct effect of interventional strategies on osteoarthritis.

Abstract
OBJECTIVE To evaluate that single photon emission computed tomography (SPECT) could reflect the clinical severity of knee osteoarthritis (OA) and to determine the clinical usefulness of SPECT as a sensitive imaging method detecting early OA. METHODS Sixty knees of thirty OA patients were examined with (99m)Tc-methylene diphosphonate (MDP) bone SPECT, the intensity of uptake was graded and the sites of uptake were localized. One hundred millimeter visual analog scale (VAS), Western Ontario McMaster Universities (WOMAC) Osteoarthritis Index scores and physical examination were assessed. Simple radiograph and musculoskeletal ultrasonography (US) were performed, and Kellgren-Lawrence (K-L) grades were determined. The relationships between clinical findings, simple radiographic findings, US findings and the intensity of uptake in SPECT were analyzed. RESULTS There were increased uptakes in 91.7% of the knees, and patella and medial tibial condyle were the most common sites of the uptakes. Symptomatic knees had significantly higher intensity of uptake than asymptomatic knees. Uptake intensity of medial compartment in SPECT well correlated with clinical findings, such as VAS, WOMAC scores, and physical examination, as well as US findings. Even in the symptomatic knees without abnormal radiographic findings, the increased uptake was observed in SPECT. CONCLUSION In patients with knee OA, SPECT findings are well correlated with clinical findings, such as pain scores and physical examinations, and SPECT appears to be a sensitive tool for early detection of knee OA. SPECT information could be useful for determining clinical severity of knee OA and for diagnosing early OA more effectively.

Abstract
Background Scintigraphy has been considered as competitive to MRI, but limited data are available on the accuracy of single photon emission tomography (SPECT) compared with MRI for the assessment of meniscal tears. Our objective was to assess the value of SPECT in comparison to MRI. Methods Between January 2003 and March 2004, sixteen patients were studied with both modalities and the accuracy rates of SPECT scan results, and MRI findings in the diagnosis of meniscal tears were compared. Arthroscopy was the gold standard. Results The respective sensitivity rate, specificity rate, and positive and negative predictive accuracies of MRI were 89%, 94%, 93%, and 79% and for SPECT those were 78%, 94%, 94%, and 88%. There was good agreement on the presence or absence of tears between two modalities (κ statistic = 0.699). Conclusion SPECT and MRI are both valuable imaging techniques. SPECT is a useful alternative when MRI is unavailable or unsuitable and it is beneficial when more possible accuracy is desired (such as when MRI results are either inconclusive or conflict with other clinical data).

Abstract
PURPOSE To evaluate the role of single photon emission computed tomography (SPECT) bone scan for the diagnosis of knee lesions in routine clinical practice. METHODS 40 consecutive case records were examined in patients who underwent a SPECT scan prior to knee arthroscopy in routine clinical practice. The accuracy of clinical examination, SPECT scan results, and arthroscopic findings (as the gold standard) in diagnosing knee lesions were compared. RESULTS The sensitivity of SPECT scans in detecting medial meniscal, lateral meniscal, anterior cruciate ligament lesions, osteochondral defects, and chondromalacia patellae was 77%, 14%, 33%, 50%, and 74%, respectively. The specificities for the same structural lesions were high at 89%, 94%, 97%, 94%, and 69%, respectively. CONCLUSION SPECT bone scan appears to be useful in the diagnosis of knee pathology in routine practice and in selecting patients for arthroscopy, especially most useful for the diagnosis of medial meniscal tears.
