Lumbar Foraminal Stenosis

Background Both multidetector computed tomography (MDCT) and magnetic resonance imaging (MRI) are used for assessment of lumbar foraminal stenosis (LFS). Therefore, it is relevant to assess agreement between these imaging modalities. Purpose To determine intermodality, inter-, and intra-observer agreement for assessment of LFS on MDCT and MRI. Material and Methods A total of 120 foramina in 20 patients who visited our institution in January and February 2014 were evaluated by six radiologists with different levels of experience. Radiologists evaluated presence and severity of LFS on sagittal CT and MR images according to a previously published LFS grading system. Intermodality agreement was analyzed by using weighted kappa statistics, while inter- and intra-observer agreement were analyzed by using intraclass correlation coefficients (ICCs) and kappa statistics. Results Overall intermodality agreement was moderate to good (kappa, 0.478–0.765). In particular, two professors and one fellow tended to overestimate the degree of LFS on CT compared with MRI. For inter-observer agreement of all six observers, ICCs indicated excellent agreement for both CT (0.774) and MRI (0.771), while Fleiss’ kappa values showed moderate agreement for CT (0.482) and MRI (0.575). There was better agreement between professors and fellows compared with residents. For intra-observer agreement, ICCs indicated excellent agreement, while kappa values showed good to excellent agreement for both CT and MRI. Conclusion MDCT was comparable to MRI for diagnosis and assessment of LFS, especially for experienced observers. However, there was a tendency to overestimate the degree of LFS on MDCT compared with MRI.

Abstract A case of trigeminal root neurinoma presenting as atypical trigeminal neuralgia was reported. The orbicularis oculi reflex was absent on the affected side, but reappeared after operation. The demonstration of the tumor was much clearer on magnetic resonance imaging. The usefulness of these electrophysiological and radiological studies in differentiating varied entities of trigeminal neuralgia is stressed. (Neurosurgery 21:733-736, 1987)

Lumbar Foraminal Stenosis (LFS) dapat secara signifikan mengurangi fungsi dan kualitas hidup pasien dan Magnetic Resonance Imaging (MRI) adalah alat pendukung yang umum digunakan untuk mengukur beratnya stenosis. Lee score umumnya digunakan untuk mengukur derajat LFS pada MRI sagital. Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) dan Oswestry Disability Index (ODI) digunakan untuk menilai disabilitas dan skor fungsional pada pasien LFS. Penelitian ini bertujuan untuk mengetahui korelasi antara derajat LFS pada MRI sagital dengan kualitas hidup pada pasien dengan LFS. Penelitian ini merupakan penelitian analitik observasional yang melibatkan 25 pasien dengan gejala klinis LFS di RS. X Surakarta. Pasien dinilai dengan mengisi kuesioner JOABPEQ dan ODI, kemudian dilakukan evaluasi MRI sagittal lumbar untuk menentukan derajat Lee score, kemudian melakukan uji korelasi pada data yang diperoleh. Penelitian ini menunjukkan korelasi yang signifikan antara Skor Lee dengan JOABPEQ dan ODI. Tingkat LFS berdasarkan Lee Score memiliki korelasi yang signifikan dengan tingkat disabilitas menggunakan JOABPEQ dan ODI. JOABPEQ memiliki korelasi yang lebih signifikan dengan Skor Lee dibandingkan dengan ODI. Kata Kunci : Lumbar Foraminal Stenosis, Lee Score, JOABPEQ, ODI Lumbar Foraminal Stenosis (LFS) can significantly reduce the patient’s function and quality of life and Magnetic Resonance Imaging (MRI) is commonly used supporting tool to measure the degree of stenosis. Lee Score is commonly used to measure the degree of LFS on sagittal MRI. Japanese Orthopaedic Association Back Pain Evaluation Questionnaire (JOABPEQ) and Oswestry Disability Index (ODI) to assess disability and functional scores in LFS patients.

Summary Objective: To examine conventional magnetic resonance imaging planes of the lumbosacral foramina to obtain objective measurements of foraminal size in mediumsized (20–28 kg) normal dogs. Method: Ten canine cadavers were evaluated using magnetic resonance imaging in neutral, flexed and extended position. Foraminal ratios, areas and lumbosacral angles were calculated and their relationship to body weight was evaluated. Results: Foraminal ratios were found to be independent of body weight in medium sized dogs (p >0.42). Foraminal areas were dependent on body weight (p <0.05). Flexion and extension were shown to significantly change both the foraminal ratio and area. Clinical significance: Lumbosacral foraminal stenosis is common in working dogs. Foraminal ratios were evaluated in mediumsized dogs and were found to be independent of body weight, which may provide objective evaluation of surgical decompression techniques if calculated pre- and post-surgery. Foraminal areas were not independent of body weight.

Abstract Objective To promote a better radiological interpretation of spine degeneration, a consistent standardization of the acquisition, interpretation and description of Magnetic Resonance Imaging (MRI) l findings. Materials and methods In order to achieve this objective, a consensus among experts in imaging of degenerative spine disease (DSD) from Italian radiological societies (SIRM—Italian Society of Radiology, AINR—Italian Association of Neuroradiology) was achieved. The representatives of the Italian inter-societal working group examined the literature produced by European/American task forces on optimizing the study sequences, classification of degenerative disc changes, spondylo-arthrosis, osteochondrosis, synovial and ligament pathologies of the spinal column, and on canal and foraminal stenosis. The document-resulted from the consensus between experts—was then presented to the scientific societies of Neurosurgery (SINCH) and Orthopedics and Traumatology (SIOT) for their approval. Results This position paper presents a proposal for an optimized MRI protocol for studying DSD and provides a glossary of terms related to this pathology and indications on their use. The international terminological recommendations have been translated and adapted to the Italian language and clinical practice and clinical cases have been used to illustrate some of the main classifications. Conclusions This revision of international DSD guidelines/recommendations and consensus made it possible to (1) update the nomenclature to international standards and (2) harmonize the MRI protocol and description of radiological findings, adapting both (1, 2) to the Italian context. With this position paper we intend to contribute to an improvement of the communication among doctors and between physicians and their patients as well as the quality of the radiological reports.
